A particle is dropped from a height h. A constant horizontal velocity is given to the particle. Taking g to be constant everywhere, kinetic energy E of the particle w. r. t. time t is correctly shown in
A
B
D
Text Solution
Verified by ExpertsThe correct answer is:
A
As particle 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. ∝ ∝ v 2 ∝ ∝ t 2
(As v ∝ ∝ t)
So, the graph between kinetic energy and time will be parabolic in nature.
