A 8 kg block sits on a ramp inclined at 12 degrees that has a coefficient of friction of 0.5. A string runs from the block over a pulley at the top of the ramp and then hangs straight down to a suspended weight. If the block slides up the ramp at constant velocity, find the mass of the suspended weight.

A block with mass 10kg is on a ramp angled at 20 degrees above the horizontal, attached via rope to another block hanging over the top edge of the ramp (by a pulley), which is also 10kg. Wheat is the coefficient of static friction needed so that the blocks do not move? If there was no friction, what would the acceleration be?

A 9.31 kg block is placed at the top of a frictionless inclined plane angled at 14.9 degrees relative to the horizontal. When released (from rest), the block slides down the full 2.77 meter length of the incline. Calculate the speed (magnitude of the velocity) of the block at the bottom of the incline. [Start by drawing a free-body diagram for the block.] Note that all the information provided may not be necessary to solve the problem.
