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 ? A body of mass 5 kg is acted upon by two perpendicular forces 8 N and 6 N. Give the magnitude and direction of the acceleration of the body.
