A 7.68 m, 132 kg uniform ladder rests against a smooth wall. The coefficient of static fric- tion between the ladder and the ground is 0.642, and the ladder makes a 48.4◦ angle with the ground. How far up the ladder can a 528 kg person climb before the la...

A bicycle wheel has a diameter of 47.6 cm and a mass of 0.809 kg. The bicycle is placed on a stationary stand on rollers and a resistive force of 60.1 N is applied to the rim of the tire. Assume all the mass of the wheel is concentrated on the outside rad...
