3. The speed of a hockey puck decreases from 49 m/s to 43.88 m/s in coasting 15.4 macross the ice. Find the µx between the puck and the ice. (Hint: W = AKE, F = µµF)4. A pitcher hurls a 0.56-kg softball. The ball starts from rest and leaves the pitcher's hand ata speed of 23 m/s. How much work is done on the softball by the hurler's arm? (Hint:W = AKE)

Spiderman, whose mass is 80.0 kg, is dangling on the free end of a 12.0-m-long rope, the other end of which is fixed to a tree limb above. By repeatedly bending at the waist, he is able to get the rope in motion, eventually getting it to swing enough that he can reach a ledge when the rope makes a 60.0 angle with the vertical. How much work was done by the gravitational force on Spiderman in this maneuver?
