A wood block (W=1N) is given a quick push up a metal ramp (35 degrees above the horizontal), and the pushing force is removed. The block slides part of the way up the ramp, then slides back down the ramp. The coefficient of kinetic friction between the block and the ramp is 0.22.
a.) Draw a free body diagram of the forces on the block (after the pushing force is removed) as it slides up the ramp and a separate free body diagram of the forces on the block as it slides down the ramp.
b.) How does the acceleration of the block change (if at all) as it slides down the ramp as compared to the acceleration of the block as it slid up the ramp? Recall that acceleration is a vector quantity.
