A 2.9 kg block rests on a 30 degree slope and is attached by a string of negligible mass to a solid drum of mass 0.70 kg and radius 5.2 cm. as shown in the figure (Figure 1). When released, the block accelerates down the slope at 1.2 m/s^2. What is the coefficient of friction between block and slope? Express your answer using two significant figures.

A 5.00 kg block rests on a level table. The coefficient of friction between the block and the table is 0.55. A 4.00 kg mass is attached to the block by a string of negligible mass passed over a light frictionless pulley (as shown below). What is the acceleration of the block when the 4.00 kg weight is released?

12. A 3.20 kg block is attached to a light and firm string and is placed on top of a horizontal platform. A horizontal force F-45.0 N is pulling the block to the right. The coefficient of the kinetic friction between the block and the platform is 0.240. The other end of the string is connected to a block of mass 2.80 kg that is hanging straight down as shown in the figure below. The blocks are...

Block B, with mass 5.00 kg, rests on block A, with mass 8.00kg. There is no friction between the table and block A, but the coefficient of static friction between block A and B is 0.750. A "massless" string attached to block A passes over a frictionless pulley and block C is suspended from the other end of the string. If we want ALL the blocks moving together with the same acceleration, the largest possible mass that block C can...

Two blocks are connected by a string that passes over a frictionless pulley, as shown in the figure. The pulley has a mass of mp = 2.00 kg, and can be treated as a uniform solid disk that rotates about its center. Block A, with a mass = 3.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces, torques,...

In the system shown below, there is a block of mass M = 3.6 kg resting on a horizontal ledge. The coefficient of kinetic friction between the ledge and the block is 0.25. The block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging block of mass m = 2.2 kg. The pulley is a uniform disk of radius 7.9 cm and mass 0.66 kg. Find the...

A block of mass m_1 = 1.5 kg is placed on a horizontal surface. Attached to the block is a string which passes over a pulley and suspends a mass m_2 = 3.5 kg as shown in the diagram below. If the system accelerates at a = 5.2 m/s^2, what is the coefficient of kinetic friction mu_k between the horizontal surface and m_1?
