Question: The 8 - kg block is attached to link AB and rests on a moving belt. Knowing that s = s = 0 . 3

The 8-kg block is attached to link AB and rests on a moving belt. Knowing that s=s=0.30 and k=k=0.25 and neglecting the weight of the link, determine the magnitude of the horizontal force P that should be applied to the belt to maintain its motion (a) to the left, (b) to the right. (Round the final answers to one decimal place.)
