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

Options

A.
B.
C.
D.

Answer

A

Explanation

`v^2 =u^2 +g^2 t^2 implies v^2 prop t^2`
KE `prop v^2 prop t^2 implies KE prop t^2`
