Problem #2: A 2.0-kg block is on a ramp that makes an angle of 30 degrees with the horizontal. 30 (a) When the applied force is 15N: (i) What is the block's acceleration? (ii) Does the block move up or down the ramp? (iii) What is the force of the ramp on the block (normal force)? (b) What force applied upward along and parallel to the ramp, F, would allow the block to move with constant velocity if there is also a frictional force of 5N opposing the motion?
