The graph between the resistive force F acting on a body and the distance covered by the body is shown in the figure. The mass of the body is 25 kg and initial velocity is 2 m/s. When the distance covered by the body is 4m, its kinetic energy would be
Text Solution
Verified by ExpertsThe correct answer is:
D
Area under curve = 
(20) = 40 J
W = work done by resistive force F = – 40 J
– 40 = K f – K i , K i = 50 J,
so K f = 50 – 40 = 10 J
