5.5 A constant retarding force of 50 N is applied to a body of mass 20 kg moving initially with a speed of 15 m s'. How long does the body take to stop ? A constant force acting on a body of mass 3.0 kg changes its speed from 2.0 m s to 3.5 m s' in 25 s. The direction of the motion of the body remains unchanged. What is the magnitude and direction of the force ? 5.6
