The block with mass ml is set into downward motion, in the direction of the arrow as seen in figure 1. The two blocks, with masses ml and m2 respectively, are connected through a weightless rope. a) Once the block with mass ml is set in motion it is moving with constant speed. Determine the coefficient of (kinetic) friction. b) If there is no friction and block ml is set in motion determine its acceleration. Cart Bucket 30 M2
