6 A block of mass 2 0 kg kept at rest on an inclined plane of inclination 37 is pulled up the plane by applying a constant force of 20 N parallel to the incline The force acts for one second a Show that the work done by the applied force does not exceed 40 J b Find the work done by the force of gravity in that one second if the work done by the applied force is 40 J c Find the kinetic energy of the block at the instant the force ceases 2 1 10 m s
