1. Motor M exerts a constant 25-lb force on
the cable in the pulley system shown to the
left. What power is being supplied to the
motor at the instant the 35-lb load has been
raised 7 ft, assuming it started from rest. The
motor has an efficiency of 0.62.

A block of weight -300 N sits on a frictionless inclined plane, which makes an angle 31.0 with respect to the horizontal, as shown in the figure (Figure 1)A force of magnitude F-155 N appied parallel to the incine, is just sufficient to pull the block up the plane at constant speed Figure 1 of 1 Part A The block moves up an incline with constant speed. What is the total work Wal done on the block by all forces as the block moves a distance Lw3.20 m up the incline? Include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest. Express your answer numerically in joules.
