A 4kg block sitting on a flat table is attached by a string over a cylindrical pulley to a 3kg block which is hanging in the air 4 meters above the ground. The coefficient of the kinetic friction is 0.2. The radius of the wheel is 0.08 meters and its mass is 0.07kg (Assume the pulley to be a solid cylinder). I need help on the step-by-step portion. The answers follow after the questions.

a) Find the acceleration (a) of the system. 3.06m/s^2

b) Find the tensions (T1 and T2) in the upper and lower part of the string, respectively. T1=20.098 Newtons, T2=20.205 Newtons.

c) Find the total work done on the wheel by the strings. 0.43 Joules

d) Find the final angular speed of the wheel. 61.89 Radians/sec
