A 4.0 kg wood block is launched up a wooden ramp that is inclined at a 20∘ angle. The block's initial speed is 12 m/s. (coeflicient of kinetic friction for wood on wood =0.20 )
a. Draw free body diagram of the block as it goes up.
b. What vertical height does the block reach above its starting point?
c. What speed does is have when it slides back down to its starting point?
d. Draw free body diagram of the block as it slides back down.
