A particle is dropped a height h. A constant horizontal velocity is given to the particle. Taking g to be constant every where, kinetic energy E of the particle w. r. t. time t is correctly shown in

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
As perticle is projected with some velocity therefore its initial kinetic energy will not be zero.
As it moves downward under gravity then its velocity
increases with time K.E.`prop^(2)propt^(2)(As v `alphat`)
So the graph between kinetic energy and time will be parabolic in nature,
