A horizontal force of 2000N is applied to a vehicle of mass 400 kg which is initially at rest on a horizontal surface. If the total force opposing motion is constant at 800 N, calcu- late: (a) the acceleration of the vehicle, (b) the kinetic energy of the vehicle 5s after the force is first applied, (c) the total power developed 5s after the force is first applied.
