A body of mass 4 kg is moving with momentum of 
. A force of 0.2 N acts on it in the direction of motion of the body for 10 s. The increase in kinetic energy is
Text Solution
Verified by ExpertsThe correct answer is:
C
: Momentum = mass × velocity
Acceleration 
Distance travelled by the body in 10 s is
Work done, W= fd = (0.2N) (22.5m) = 4.5 J
According to work-energy theorem
Increase in kinetic energy = work done = 4.5 J
