This question involves the concept of kinetic energy.
The student's claim is "right".
<h3>Kinetic Energy</h3>
The energy possessed by a body, by the virtue of its motion is called kinetic energy. Mathematically it is given by the following formula:

where,
- K.E = Kinetic energy
- m = mass
- v = velocity
Therefore,
For the paintball:

K.E = 16200 J
For the pellet:

K.E = 16200 J
Hence, both paintball and pellet will have same kinetic energy. The student is right.

The answer is A because the paper does not change its chemical properties only changes the way it looks.
Answer:
rpm
Explanation:
Given that rotational kinetic energy = 
Mass of the fly wheel (m) = 19.7 kg
Radius of the fly wheel (r) = 0.351 m
Moment of inertia (I) = 
Rotational K.E is illustrated as 





Since 1 rpm =
