Question

32. A ball is going to fall downward through a vacuum chamber. If it has maximum potential energy at the top and maximum kinetic energy at the
bottom where along the fall will half of its maximum velocity occur?

A: At exactly halfway down

B: At more than halfway down (between halfway and the bottom)

C: At less than halfway down (between halfway and the top)

Answer 1

Half maximum velocity occurs at the point of half maximum kinetic energy which is exactly halfway down.

Conservation of energy

The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.

M.A = K.E + P.E

At the maximum height, the kinetic energy of the ball while potential energy is maximum.

At the half-way down, the ball kinetic energy of the ball is equal to the potential energy.

Thus, half maximum velocity occurs at the point of half maximum kinetic energy which is exactly halfway down.
