Answer:
This is because, when an object which has possessed kinetic energy under its being in motion hits another object, which is stationary the object at rest receives part of the energy inherent in the body which has kinetic energy and expresses the received energy in the form of motion or some forms different from the initial stationary position.

Answer:
7.6427m/s
Explanation:
Given:
#Applying the conservation of momentum along the x-axis:
#And along y-axis:
#Solving for 
:
#By substitution in the x-axis equation:
Hence the original speed of the ball before impact is 7.6427m/s
Renewable source means that it can never run out or run out in a long time. In this case the sun is expected to shine for about five billion years because of the high amount of hydrogen that is stored in its core. So the answer should be "The sun is continuously releasing energy". This answer is the best because there are many other renewable resources on earth that can cause pollution.
Answer:
a = - 3.75 m/s²
negative sign indicates deceleration here.
Explanation:
In order to find the constant deceleration of the car, as it stops, we will use the 3rd equation of motion. The 3rd equation of motion is as follows:
2as = Vf² - Vi²
a = (Vf² - Vi²)/2s
where,
a = deceleration of the car = ?
Vf = Final Velocity = 0 m/s (Since, the car finally stops)
Vi = Initial Velocity = 30 m/s
s = distance covered by the car = 120 m
Therefore,
a = [(0 m/s)² - (30 m/s)²]/(2)(120 m)
<u>a = - 3.75 m/s²</u>
<u>negative sign indicates deceleration here.</u>
Answer:
The kinetic molecular theory of matter asserts that: Matter is made up of particles that are continually moving. All particles contain energy, however the energy fluctuates depending on the temperature the sample of matter is in. This in turn decides whether the material exists in the solid, liquid, or gaseous form.
