A force of 10 N, acting continuously, increases the kinetic energy of an object from 20.J to 60 J. Find the distance moved by the object.
according to the work-energy theorem; Workdone = change in kinetic energy.
W = ∆ K.E
force x distance = \(K.E_2 - K.E_2\)
10 x s = 60 - 20
s = \(\frac{40}{10}\) = 4m.
