Students have asked these similar questions

In the figure provided, a crate of mass m sits at rest on a 20° ramp and is connected to another crate of mass 1.84 kg by a rope and pulley. If the coefficient of friction is μk = 0.510 and μs = 0.790 with the surface, what acceleration will the mass m have if it is slightly nudged and begins to be pulled up the ramp? Assume the rope and pulley are massless.

Two blocks A and B of the same mass 1.06 kg are released from rest on a 30° incline when they are S = 16.4 m apart, as shown. The coefficient of friction under the upper block A is 0.21, and that under the lower block B is 0.4. Compute the elapsed time (in seconds) until the blocks touch each other.

What happens to the coefficient of friction, when weight of the body is doubled?
