I only have 2 problems left in this chapter that I am having difficulties solving... any help is greatly appreciated!

1. Two people are pushing their stalled car up a hill with an incline of 5.00°. They are pushing parallel to the surface of the hill. The car's mass is 954 kg. What is the combined force they must apply to keep the car moving at a constant speed up the hill? Ignore the forces of friction and air resistance.

2. Two blocks are connected by an ideal string that passes over a massless, frictionless pulley. The two blocks hang freely. The first block has a mass of 14.3 kg, and the second block weighs 98.0 N. Determine (a) the magnitude of the blocks' acceleration, (b) the magnitude of the tension in the string.
