The velocity of the gold puck after the collision be (2i - j) m/s.

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

Given parameters:

Mass of the gold puck: m = 12 kg

Velocity of it before collision: u =  5i – 4j m/s.

Mass of the stationary blue puck: M = 18 kg.

Velocity of it after collision; V = 2i – 2j m/s.

We have to find:  the velocity of the gold puck after the collision: v = ?

From conservation of linear momentum, we get:

Total momentum of the system before collision =  Total momentum of the system after collision

⇒ mu + M.0 = mv + MV

⇒ v = u - MV/m

⇒ v  = (5i – 4j) m/s  - (2i – 2j)m/s×18/12.

⇒ v  = (5i – 4j) m/s - (3i - 3j) = (2i - j) m/s.

Hence velocity of the gold puck after the collision be (2i - j) m/s.

If you haven’t read about the shark found swimming in and out of a segment of an undersea volcano, then you really need to get up to date.

Explanation:

Answer:

The speed is "1447.576 mph".

Explanation:

The given values are:

Direction (north to east)

= 23°

Wind's speed

= 937 mph

Jet moving at a speed

= 538 mph

Now,

The velocity of jet airliner with respect to the ground will be:

⇒ [tex]v=v_{1}+v_{2}[/tex]

⇒ [tex]v=\sqrt{(538)^2+(987)^2+2(538)(937)\times Cos23^{\circ}}[/tex]

⇒    [tex]=1447.576 \ mph[/tex]

Hi! I believe your answer is 6.3 seconds because it takes 0.45 seconds for an object to fall 1 meter, so just multiply 0.45 by 14 and you'll get 6.3 seconds. I hope this helps you! Good luck and have a great day/night. ❤️✨

Courts often depend upon recovered memories is the wrong statement about the hypnotic regression.

Hypnotic regression is a contentious method because it can have a number of negative effects on the subjects who undergo it. For the beginners, the memories recovered through any regression can be doubtful and not trust-worthy. All the suggestions or leading questions from the hypnotist or other people of witnesses can affect the memory.

The previous lives memories will be found by the hypnotic technique as a past life regression.  If they used to remember the past life by this method they have high chance of getting into the traumas.

Regression therapy mostly used to identify the cause of your current thoughts and reactions. Therapists who is using this techniques to access subconscious memories that are guiding your current behaviour.

Regression therapy is a method of  treatment that could approach and focuses on resolving particular past events that are thought to be interfering or relatable with a person's current mental and emotional well-being.

Answer:

The parachute to open in 15 sec.

Explanation:

Given that,

Velocity = 120 km/hr

Height = 1000 m

If his parachute must open 500. m above the ground.

We need to calculate the time for parachute to open

Using formula of time

[tex]v=\dfrac{d}{t}[/tex]

[tex]t=\dfrac{d}{v}[/tex]

Where, d = distance

t = time

v = velocity

Put the value into the formula

Mostly with aid of Kohlberg 's moral growth theory, I clarify this answer, which would also be separated into three stages under which this particular problem is illustrated below.

Explanation:

The daughter's father would think about either the penalty during that point if he commits any wrongdoing or breaches laws to save her daughter. But another way to make that happen for surgery is that a person cares about either the legislation and rules as well as the significance of respecting them throughout the pre-conventional process. He will also attempt to establish its insight into solving these problems.

As per the traditional process of the spiritual psychosocial development of Kohlberg, her father would think of civilization because there are conventions that unless he borrows money of his dad again for the procedure of their daughter, culture would label him greedy or prejudice against him to pay the profits of his father despite his consideration.

As per this argument, he might determine for her child as well as father in his philosophy including perspectives, which means that his father is not in the situation of requesting credit, but because he's in a position to give a recommendation, therefore he certainly gives authorization rescue her grandchildren even though she is small and has several activities to do in hers life. And subsequently, with emerging profits, he will take care of his father as well as daughter, and nowadays focus says their daughter wants treatment to recover.

Answer:

Gravitational pulls things to the ground

Elastic is stretched or compressed or a shape or object

Kinetic is kinda like the force of motion

Hope this helps

In the gravitational energy, things are pulled to the ground by gravity, for elastic energy stretched, squeezed, or as a shape or item, and for kinetic energy it is similar to the force of motion.

Kinetic energy is the term used in mechanics to describe the impulse that an object experiences as it moves. It is described as the amount of effort needed to move someone of a certain mass to rest to a given velocity. Except for fluctuations in speed, the body retains its acceleration after receiving it during acceleration.

The body uses the same lot of fuel when slowing down from its current rate to a state of rest. Formally, kinetic energy refers to any element in the Lagrangian of such a system that seems to have a derivative with respect to time.

What we want to do here is to basically put in words in the select pane that could actually beat complete the question.

The higher the distance between the effort and the function of a lever, the higher the force needed to complete the work.

The smaller the distance between the effort force and the fulcrum of a lever, the smaller the mechanical advantage , making the work easier

If a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s², then he was moving at  31 m / s at the bottom of the course.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

As given in the problem, a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s² .

By using the first equation of the motion,

v = u + at

v = 1 + 3 × 10

v = 31 m / s

Thus, he was moving at  31 m / s at the bottom of the course.

Answer:

(1) The acceleration is 1.72 m/s²

(2) (a) The change in speed is 1.8 m/s

(2) (b) The acceleration is 0.563 m/s²

Explanation:

(1)

Given;

initial velocity, u = 1.5 m/s

final velocity, v = 18 m/s

time of motion, t = 9.6 s

The acceleration is given by;

a = (v - u) / t

a = (18 - 1.5) / 9.6

a = 1.72 m/s²

(2)

Given;

initial speed, u = 2.2 m/s

final speed, v = 4 m/s

time of motion, t = 3.2 s

(a) The change in speed is given by;

Δv = v - u

Δv = 4 m/s  - 2.2 m/s

Δv = 1.8 m/s

(b) the acceleration is given by;

a = Δv / t

a = 1.8 / 3.2

a = 0.563 m/s²
