A conveyer belt making an angle of 30 degree with the horizontal moves up with a speed of 3 m/s. A box is gently placed on it. The coefficient of friction between the belt and the box is 0.8, then1-relative velocity of the box is 3 m/s down the belt2-acc. of the box is approximately 2m/s3-distance moved by the block before coming to rest is 3.4 m4-net force acting on the belt is down the belt
