A 2.00-kg block is tied to a wall and placed on top of a 5.00-kg block, as shown. A horizontal force of 55.0 N is applied to the 5.00-kg block. There is a coefficient of kinetic friction of 0.250 between all moving surfaces. Determine (a) the tension in the string and (b) the acceleration of the 5.00-kg block. ANSWER IS: a) 4.90 N; (b) –6.59 m/s2

A
massless rope is tied to a 14kg block is draped over a pulley. The
51kg pulley has a radius of 47 cm and the pulley rotates so that
the rope does not slip on the pulley. The right side of the rope is
pulled down with a tension of 303N. What is the acceleration of the
block? You may treat the pulley as a disk. Ignore any frictional
torque in the axle.

The cable cars in San Francisco are pulled along their tracks by an underground steel cable that moves along at 9.5 mph. The cable is driven by large motors at a central power station and extends, via an intricate pulley arrangement, for several miles beneath the city streets. The length of a cable stretches by up to 100 ft during its lifetime. To keep the tension constant, the cable passes around a 1.5-m-diameter "tensioning pulley" that rolls back and forth...
