Block 1 of mass m is on top of block 2 of mass 5m as shown in the figure. Block 2 is on a horizontal smooth plane, and a rope can pull horizontally on block 2. The static and kinetic friction coefficients between the surfaces of the two blocks are 5/8 and 1/2 respectively. What is the resulting acceleration of block 2 if a force F=4mg with g being the acceleration of gravity is applied to the rope?

Basically the diagram is block 1 on top of block 2 (which is on the floor). There's a force being exerted on block 2 to the right from the rope. Thanks. :)

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?
