Question

A block of mass 120 kg is resting on a rough horizontal surface.The coefficient of static friction between the block and thehorizontal surface is 0.50. The co efficient of kinetic friction is0.30. You attempt to move the block by pulling on a rope that isattached to the block at an angle of 25 degrees above thehorizontal.

A. How much force on the rope is needed to start the blockmoving?

B. If this force is maintained after the block starts moving whatis the acceleration of the block?

Please show final answer and all work done to get that answer
