A force F is applied to a block to move it up a θ = 27° inclined frictionless surface. If F = 72 Newton, and M =4.2 kg, what is the magnitude of the acceleration of the block?

A block is placed on the midpoint of a ramp that is inclined at an angle of 39.8º from the horizontal, at which point the block immediately starts to slide down the ramp due to the fact that the static friction limit for this particular case is insufficient to hold the block in place. If the coefficient of kinetic friction between the block and the ramp is  0.277 , what is the magnitude of the acceleration of the block as it slides down the ramp.
