A pulley system is attached securely to the corner of a ceiling and connects to masses M_1 and M_3 as shown. Under M_3 sits another mass, M_2. Mass M_1 rests on a 65 degree incline, while masses M_2 and M_3 are on a 23 degree incline. The coefficient of kinetic friction between the masses and the inclines is mu _k = 0.10, while the coefficient of static friction between M_2 and M_3 is mu _s = 0.90. If M_2 =...

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?

This is a physics question about applying Newton's Laws. So the question involves a pulley system in which two blocks are connected by a string. One block is on a horizontal flat plane with a mass of 7.8kg. The block and horizontal surface has a coefficient of kinetic friction of .87. The second block is on an incline that has a 35 degree angle the block that is on this incline has a mass of 4.8 kg. This incline is...

Two masses are being pulled up a 30.0 degree incline by a force F parallel to the incline. The acceleration down the incline is 1.00 m/s2 and the velocity is up the incline. The force is applied to a 200 kg mass, and a string connects the 200 kg mass to a 150 kg mass. The coefficient of kinetic friction is 0.200. What is the tension in the string? answer: 840 N

Write clearly, explain well.
Problem 1: Masses, friction inclines, and a pulley (5 points) A solid cylinder of mass (m) and radius (r) is on a plane inclined at an angle (0). The cylinder has a string wrapped around it and attached to a wall at the top of the incline. The string runs parallel to the incline. There is a coefficient of kinetic friction (uk) between the cylinder and the plane. The cylinder begins to slide and unravel the...
Two blocks with masses M1 and M2 are connected by a massless string that passes over a massless pulley as shown
Two blocks with masses M1 and M2 are connected by a massless string that passes over a massless pulley as shown. M1 has a mass of 2.25 kg and is on an incline of θ1=43.5° with coefficient of kinetic friction μ1=0.205 . M2 has a mass of 6.15 kg and is on an incline of θ2=35.5° with coefficient of kinetic friction μ2=0.105. The two-block system is in motion with the block of mass M2 sliding down the ramp.Find the magnitude...
