Return to Example 9.9 and use the result to find the tension in the rope.
Example 9.9 Snow Tubing
At a winter recreation resort, snow tubers at the bottom of the hill hook their tubes to a tow rope. A motor pulls the rope so that tubers move at constant velocity to the top of the hill. (Ignore the momentary acceleration of the tuber when he first attaches his tube to the rope.) The coefficient of kinetic friction between the tube and the snow is μk = 0.16. A boy and his tube with a total weight of 415 N are pulled a distance of 255 m up the 18° incline (Fig. 9.29). Consider the Earth, the boy, his tube, and the snow along his path to make up the system. Find the energy transferred from the motor to the system via the work done by the rope.

- Here we have successfully built up a problem that uses one topic from each of the four quarters of material we have covered. A block with mass m1 = 3.00 kg sits on a horizontal table and is attached to a rope. The rope then passes over a MASSIVE pulley and is attached to a block of mass m2 = 2.00 kg, which hangs vertically (see picture). The coefficient of kinetic friction of the interface between the table and m1 is 0.1. You may assume the pulley section is a disk with a mass of 2.00 kg. We will keep the pulley frictionless for brevity. This time, however, m1 is a piston attached to an isolated volume of air that is heated in such a way that the air is always allowed to expand ISOBARICALLY. The pressure of air inside AND outside the chamber is 1 atm. The initial volume of air is 0.100 m^3 . The cross-sectional area of the m1 piston on either side perpendicular to its motion is 0.0100 meters. a) Find the acceleration of the blocks using Newton’s Laws (no radius needed)arrow_forwardUse g = 10 m/s/s in the following problems.

(b) Would the coefficient of friction calculated in part (a) be sufficient to prevent a hollow ball (such as a soccer ball) from slipping? Justify your answer. (c) In part (a), why did we use the coefficient of static friction and not the coefficient of kinetic friction?arrow_forwardOne end (A) of a thin rod rests on a floor, with coefficient of static friction μs. The other end (B) of the rod leans against a frictionless wall. The rod has a length of L and a mass of m. The rod has a uniform density, so the center-of-mass is a distance L/2 from either end.
