A block of mass 2.0 kg kept at rest on an inclined plane of inclination `37^0` is pulledup 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 work done by the applied force is 40 J. c. Find the kinetic energy of he block at the instant the force ceases to act. Take `g=10 m/s^2`.

A block of mass 2.0 kg is pushed down an inclined plane of inclination 37^0 with a force of 20N acting parallel to the incline. It is found that the block moves on the incline with an acceleration of 10 m/s^2 . If the block started from rest, find the work done by the applied force in the first second .

A block of mass 5.0 kg slides down an incline of inclination 30^0 and length 10 m. find the work done by the force of gravity.
