Chapter 6, Problem 23P
Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. A 9.0 kg gibbon has an arm length (hand to shoulder) of 0.60 m. We can model its motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. At the lowest point of its swing, the gibbon is moving at 3.5 m/s. What upward force must a branch provide to support the swinging gibbon?

Two blocks are connected by a massless string that passes through the center of a rotating turntable. The blocks have masses M1 = 1.1 kg and M2 = 2.9 kg. Block 1 rests a distance r = 0.44 m from the center of the turntable. The coefficient of static friction between block and turntable is us = 0.69. Block 2 hangs vertically below.

- Consider the Atwood machine shown in the figure, where m1 = 2.00 kg and m2 = 5.00 kg. The system starts at rest, then the sphere is given a quick push downward, giving it an initial speed of 2.45 m/s. Assume the pulley and cord are massless, and the cord is inextensible. Neglect friction.

At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?arrow_forwardWhile moving into his new house, Voytek is sliding a heavy box of books across his bedroom floor. He turns to his little sister, Silvia, and says: “It is always harder to start to move an object that is initially at rest across a horizontal surface than it is to keep that same object moving.” Which statement correctly explains this effect?arrow_forward

The slope is angled at eight degrees to the horizontal. They both start from the same position at the same time, and slide down the icy slope entirely due to gravity alone. There is a coefficient of kinetic friction of 0.12 between the penguins and the ice.

- In the situation described in Problem 45 and Figure P4.45, the masses of the rope, spring balance, and pulley are negligible. Nicks feet are not touching the ground. (a) Assume Nick is momentarily at rest when he stops pulling down on the rope and passes the end of the rope to another child, of weight 440 N, who is standing on the ground next to him. The rope does not break. Describe the ensuing motion. (b) Instead, assume Nick is momentarily at rest when he ties the end of the rope to a strong hook projecting from the tree trunk. Explain why this action can make the rope break.
