A 5.0 kg block is on a perfectly smooth ramp that makes an angle of 31° with the horizontal. (a) What is the block's acceleration (in m/s2) down the ramp? (Enter the magnitude in m/s^2.) (b) What is the force (in N) of the ramp on the block? (Enter the magnitude in N.) (c) What force (in N) applied upward along and parallel to the ramp would allow the block to move with constant velocity? (Enter the magnitude.)

A block whose weight is 42.6 N rests on a horizontal table. A horizontal force of 34.1 N is applied to the block. The coefficients of static and kinetic friction are 0.640 and 0.390, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? If the block does not move, give 0 m/s2 as the acceleration.
