Question
An object is falling from a terrace of height 20m. At what point does it have maximum kinetic energy?
Answer: Option D
:
D
When the object isat a height of 20m above the ground, it has only potential energy.
Since the velocity of the object increases when it comes down, its kinetic energy will increase. When theobject is just about to touchthe ground, its potential energy will be zeroand kinetic energy will be maximum.
