A cord connected at one end to a block which can slide on an inclined plane has its other end wrapped around a cylinder resting in a depression at the top of the plane.

 

Part A

Determine the speed of the block after it has traveled $1\mathrm{.}50m$ along the plane, starting from rest. Assume there is no friction.

Express your answer using two significant figures.

Part B

Determine the speed of the block after it has traveled $1\mathrm{.}50$m along the plane, starting from rest. Assume the coefficient of friction between all surfaces is $=0\mathrm{.}0270.$ Since the block is much lighter than the cylinder, ignore tension in the string when calculating the normal force on the cylinder. Do not ignore tension in the string when calculating the net torque $($including friction$)$ on the cylinder.
