A block m1 = 10.0 kg rests on another block m2 = 50.0 kg. Block m1 is pushed at a respective angle of 30 degrees to the horizontal. The static friction coefficient between the two blocks is us = 0.600. What must be the maximum force exerted on block m1 to prevent it from sliding on block m2? Friction between the table and mass m2 is negligible. No friction m m 30°

M // 124 N at a downward angle 0 40° You are pushing a block with force F from the horizontal and your friend is pulling the same block with force F2 162 N horizontally in the same direction. The block has mass m = 53.0 kg and is moving with acceleration a in the direction of the exerted force F2. If the coefficient of kinetic friction uk .250 between the block and the floor, what is the magnitude of acceleration đ that the block experiences?

In a movie, a stuntman places himself on the vertical front of a truck as the truck accelerates. The coefficient of static friction between the stuntman and the truck is 0.370. The stuntman is not standing on anything but can “stick” to the front of the truck as long as the truck continues to accelerate. What minimum forward acceleration will keep the stuntman on the front of the truck?

A block is sliding down a ramp at an angle of 0 = 16° to the horizontal. Its initial speed is 2.8 m/s. After sliding 13.6 m along the ramp, it comes to a rest. What is the coefficient of kinetic friction, µ., between the block and the ramp? Ө

The drawing shows a cube (mass=26.6kg), being accelerated across a horizontal frictionless surface by a horizontal surface P. A small cube (mass= 4.4kg) is in contact with the front surface of the large cube and will slide downward unless P is sufficiently large. The coefficient of static friction between the cubes is 0.710. What is the smallest magnitude that P can have in order to keep the small cube from sliding downward?

A 489-kg crate is placed on an adjustable inclined plane. As one end of the incline is raised, the crate begins to move downward. If the crate slides down the plane with an acceleration of 0.08 m/s2 when the incline angle is 31°, what is the coefficient of kinetic friction between ramp and crate? (g = 9.8 m/s2)

A large cube (mass = M) being accelerated across a horizontal frictionless surface by a horizontal force . A small cube (mass = m) is in contact with the front surface of the large cube and will slide downward unless is sufficiently large. The coefficient of static friction between the cubes is u. What is the smallest magnitude that F can have in order to keep the small cube from sliding downward?

Block 1 (10 kg) is pulled by a rope from left to right up a ramp which is inclined 50 degrees from the horizontal. The rope pulls on block 1 with a force of 150 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.3. Weight force on block 1 by EarthW1E =  i +  j N Tension force on block 1 by RopeT1R =  i +  j N Normal force on block 1 by SurfaceN1S =  i +  j N Frictional force on block 1 by Surfacef1S =  i +  j N What is the acceleration a of block 1?a =  i +  j m/s2

Scenario: You pull on a 7.9 kg block with a rope exerting a 34 N tension force that is directed 16 degrees above horizontal. If you were to pull the tiniest bit harder, the block would move, but at this tension the block stays put. Question: What is the coefficient of static friction between the block and floor?
