a. (a) A body of mass 2 kg is accelerated from rest to a speed of 3 m/s. Calculate the work done on the body in this stage.
b. (b) The same body is then accelerated further from 3 m/s to 5 m/s. Calculate the additional work done in this stage.
c. (c) Find the percentage increase in the kinetic energy of the body from 3 m/s to 5 m/s.
