MATHEMATICS Final: A 22-kg object is suspended from a spring with k= 18

Consider the motion of ball down an inclined plane and determine at which position will it have maximum kinetic energy?

Consider the following statements and mark the statement as you answer which is correct in the context of kinetic energy and potential energy.

1. The kinetic energy of a molecule depends on the temperature while potential energy depends upon the position

2. The kinetic energy of an object is due to its position while potential energy is due to its velocity

3.  Both kinetic and potential energy of an object can be maximum at the same time

4. None of these

Identify two true statements about projectiles among the following

1. The horizontal component of velocity always remains constant during projectile

2. The vertical component of velocity remains constant during projectile

3. The vertical component of velocity changes due to the downward gravity

4. The kinetic energy becomes zero at maximum height
