A tightrope walker is walking between two buildings holding a pole with length ?=14.5 m and mass ?p =19.5 kg. The daredevil grips the pole with each hand a distance ?=0.590 m from the center of the pole. A bird of mass ?b =565 g lands on the very end of the left‑hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force ?left and ?right must the left and right hand exert to counteract the torque of the bird?

A 40.0 kg boy sits on a seesaw 3.0 m away from the pivot point. The mass of the wooden plank is 5.0 kg. A 30 kg boy sits opposite the 40.0 kg boy to balance the seesaw. What is the normal force exerted by the pivot point? g = 9.8
Can you draw a free-body diagram of this problem? Three children are trying to balance on a seesaw, which includes a fulcrum rock acting as a pivot at the center, and a very light board 3.2 m long as shown in the figure. Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw?

Pete Zaria works on weekends at Barnaby's Pizza Parlor. His primary responsibility is to fill drink orders for customers. He fills a pitcher full of Cola, places it on the counter top and gives the 2.6-kg pitcher a 7.8 N forward push over a distance of 36 cm (0.36 m) to send it to a customer at the end of the counter. The coefficient of friction between the pitcher and the counter top is 0.25. a. Determine the work done by Pete on the pitcher during the 36 cm push. b. Determine the work done by friction upon the pitcher. c. Determine the total work done upon the pitcher. d. Determine the kinetic energy of the pitcher when Pete is done pushing it. e. Determine the speed of the pitcher when Pete is done pushing it.
