Neglect all friction, except that at the worker's feet. The acceleration a is positive if up the slope, negative if down the slope.

Block A has a weight of 60 lb and block B has a weight of 10 lb. Neglect friction and the mass of the cord and pulleys. The figure shows a system of pulleys and blocks. Block A is located on an inclined surface with a slope of three-fourths. Block B is vertically suspended by a cord that goes over a pulley located at the top end of the inclined surface. The cord then goes downward and to the left, parallel to the slope, then it goes over a pulley fixed to the upper right end of block A. Then the cord goes upward and to the right parallel to the slope. The end of the cord is fixed to the anchor. Determine the speed of block A after it moves 5.7 ft down the plane, starting from rest.
