*71. D A 61-kg snow skier is being pulled up a 12° slope by a steel cable. The cable has a cross-sectional area of 7.8 × 10-5 m². The cable applies a force to the skier, and, in doing so, the cable stretches by 2.0 X 10-* m. A frictional force of magnitude 68 N acts on the skis and is directed opposite to the skier's motion. If the skicr's acceleration up the slope has a magnitude of 1.1 m/s², what is the original (unstretched) length of the cable?

Your cat "Ms." (mass 7.00 kg) is trying to make it to the top of a frictionless ramp 2.00 m long and inclined upward at 30.0 ° above the horizontal. Since the poor cat can't get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 100 N force parallel to the Part A If Ms. takes a running start so that she is moving at 2.40 m/s at the bottom of the ramp, what is her speed when she reaches the top of the incline? Use the work-energy theorem. ramp. m/s
Two blocks with masses, mi and ma, are connected by a massless, un- stretchable rope. They are being hauled up an inclines plane by a constant force of magnitude F, connected to the blocks by another massless, unstretchable rope that goes over a frictionless pulley.

The angle of the inclined plane is defined in the figure below. a. Find the acceleration of the blocks b. Find the tension in the rope connecting the two blocks. c. Suppose the magnitude F was not large enough to move the blocks up the plane but large enough so that the blocks did not slide down the plane. Find all the forces actin on the block with mass mi
