A mass of 4 kg goes down an incline at angle 27 degrees (see
picture). Coefficient of kinetic friction of mass and incline is
0.195. A string with tension is on the mass and pulley (mass of
7 kg) with a radius of 0.11 m.
The centre of the pulley rotates around a piece holding it in
place. (ignore any static friction)
a) draw a free body diagram of this
b) find acceleration of the mass (m1)
c) Find angular acceleration of pulley
d) Find tension in the string
