A block lying on a long horizontal conveyer belt moving at a constant velocity receives a velocity v_(0) = 5m//s relative to the ground in the direction opposite to the direction of motion of the conveyer. After t = 4s , the velocity of the block becomes equal to the velocity of the belt. The coefficient of friction between the block and the belt is mu = 0.2 . Determine the velocity v of the conveyer belt.

Figure. shows a rough horizontal plane which ends in a vertical wall, to which a spring is connected, having a force constant k. Initially spring is in its relaxed state. A block of mass m starts with an initial velocity u towards the spring from a distance l_(0) from the end of spring shown. When block strikes at the end ofthe spring, it compresses the spring and comes to rest. Find the maximum compression in the spring. The friction coefficient between the block and the floor is mu ..
