A particle of mass 2 kg starts moving in...

A particle of mass `2 kg` starts moving in a straight line with an initial velocity of `2 m//s` at a constant acceleration of `2 m//s^(2)`. Then rate of change of kinetic energy.

A

is four times the velocity at any moment

B

is two times the displacement at any moment

C

is four times the rate of change of velocity at any moment

D

is constant throughout

Text Solution

Verified by Experts

The correct Answer is:
A
`F = ma = 2 xx 2 = 4 N ," "` Rate of change of KE = rate of work done by F
`F = Fv = 4v`.
