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?
A 5.8- kg concrete block rests on a level table. A 3.9- kg mass is attached to the block by a string passing over a light, frictionless pulley. If the acceleration of the block is measured to be 1.4 m/s2, what is the coefficient of friction between the block and the table?
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?
A block of mass 59.1 kg rests on a slope having an angle of elevation of 28.3°. If pushing downhill on the block with a force just exceeding 177 N and parallel to the slope is sufficient to cause the block to start moving, find the coefficient of static friction.
A block of mass 58.1 kg rests on a slope having an angle of elevation of 24.3°. If pushing downhill on the block with a force just exceeding 192 N and parallel to the slope is sufficient to cause the block to start moving, find the coefficient of static friction. HINT
help! (22 POINTS) 3 ) A block with a mass of 20 kg rests on a hill inclined at 30P to the horizontal. The coefficient of static friction is 0.25 and the coefficient of kinetic friction is 0.15. What is the magnitude of a force (Fa), applied parallel to the incline, needed to move the block UP the hill at a constant velocity? Express your answer in Newtons using 3 significant figures.

A block A with a mass of 3 kg rests on a horizontal table top. The coefficient of kinetic friction, μk = 0.5. A horizontal string is attached to A and passes over a massless, frictionless pulley, and block B with mass 2 kg hangs from it. Because of the pull of gravity, the masses accelerate. What is the Tension in the string (in Newtons)?
3. A 5.00 kg block rests on a level frictionless surface and is attached by a light string to an 7.00 kg hanging mass where the string passes over a massless, frictionless pulley. Ifg=9.80 m/s, what is the tension in the connecting string? 4. A light string connects a 16 kg mass and a 4.0 kg mass over a massless, frictionless pulley.

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...
