Textbook Question
Chapter 13.4, Problem 45P

If the force exerted on cable AB by the motor is F = (100t3/2) N, where t is in seconds, determine the 50-kg crate’s velocity when t = 5 s. The coefficients of static and kinetic friction between the crate and the ground are μs = 0.4 μk = 0.3, respectively. Initially the crate is at rest.

The force F, acting in a constant direction on the 24-kg block, has a magnitude which varies with the position s of the block. When s = 0 the block is moving to the right at v = 6 m/s. The coefficient of kinetic friction between the block and surface is μk = 0.3. Determine how far the block must slide before its velocity becomes 15 m/s. No hand written solution and no image
If motor M exerts a force of F = (10t2+ 100) N on the cable, where t is in seconds, determine the velocity of the 25-kg crate when t = 4 s. The coefficients of static and kinetic friction between the crate and the plane are μs = 0.3 and μk = 0.25, respectively. The crate is initially at rest.
The conveyor belt is moving at 4 m/s. If the coefficient of static friction between the conveyor and the 10-kg package B is ms = 0.2, determine the shortest time the belt can stop so that the package does not slide on the belt.
