Question
An object is thrown upward to a person on a roof. A.) At what point is the object's kinetic energy at maximum? (when the object is released OR when the object reaches its greatest height?) B.) At what point is the potential energy of the system at maximum? (when the object is released OR when the object reaches its greatest height?) C.) At what point is the object's kinetic energy at minimum?(when the object is released OR when the object reaches its greatest height?) D.) At what point is the potential energy of the system at minimum? (when the object is released OR when the object reaches its greatest height?)
Explanation / Answer
(a)
The Kinetic Energy of the object thrown upward to a person would be maximum when the object is released.
(b)
The Potential Energy of the object thrown upward to a person would be maximum when the object reaches maximum or greatest height.
(c)
The Kinetic Energy of the object thrown upward to a person would be minimum when the object reaches maximum or greatest height.
(d)
The Potential Energy of the object thrown upward to a person would be minimum when the object is released.
