Suppose the block of the previous problem is pushed down the incine witas force of 4N. How far will the block move in the first two seconds after starting from rest? The mass of the block is 4 kg.

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 a. by the applied force in the first second b. by the weight of the block in the first second and c. by the frictional force acting on the block in the first second. Take g=10 m/s^2 .

A man wants to slide down a block of mass m which is kept on a fixed inclined plane of inclination 30^(@) as shown in the figure .Initially the block is not sliding . To just start sliding the man pushed the block down the inclined with a force F . Now , the block starts accelerating. To move it downwards with conatant speed the man starts pulling the block with same force. Surface are such that ratio of maximum static friction to kinetic friction is 2 Now, answer the following questions. If the man continues pushing the block by force F its acceleration would be
