General Physics
The 5 kg block in the figure slides down a frictionless curved ramp, starting from rest at a height of h = 3 m. The block then slides d = 12 m on a rough horizontal surface before coming to rest.What is the coefficient of friction between the block and the horizontal surface?

A 500 g block on a frictionless surface is attached to a rather limp spring of constant k = 8.7 N/m. A second block rests on the first, and the whole system executes simple harmonic motion with a period of 3.1 s. When the amplitude of the motion is increased to 60 cm, the ...

A 50-kg block is at rest on a 15 degree slope. A force of 250 N is acting on the block up the slope parallel to it. If the block does not slide up the slope, what is the minimum value of the coefficient of static friction between the block and the slope?

If a block of mass 10.0 kg rests on a horizontal surface, and the coefficient of static friction is 0.300, what is the maximum static friction that can act on the block? If you could walk me step by step on completing this problem, I would be extremely grateful and it would be...
