Physics: Law of Motion 2 Questions; review and tutorial

2. A sled accelerates down a hill with a nonzero coefficient of kinetic friction uk. Derive an expression for the sled's acceleration in terms of g, 0, and uk. (Where 0 is the angle of the hill). 3. Block A (mass mA = 8.00 kg) is moving on a frictionless 30.0 incline. This block is connected to block B (mass mp= 22.0 kg) by a massless cord that passes over a massless and frictionless pulley. Find the acceleration of each block and the tension in the cord
