"The potential energy of a 4 kg object on top of a hill is 72 J. What is its velocity in m/s just before it hits the ground? a. 36 b. 18 c. 6 d. 3"   Answer: The velocity in the problem wherein a 4kg object on top of the hill has a potential energy of 72J is c. 6m/s. Explanation: The first step that we will do is to understand the concepts of kinetic energy and potential energy. Kinetic energy is the work that an object should have in order for it to be in motion or accelerate. Simply, kinetic energy is the object's energy caused by its movement in space. The energy is invested through its acceleration and maintains its magnitude unless a change of velocity occurs. The kinetic energy of an object will be set to 0 once it is placed into rest. On the other hand, potential energy is the energy that an object contains within itself which is dependent on its mass, distance from a relative mass or point of reference, and gravitational pull. Given its definition,...
