a Make a copy of the figure, and on it draw arrows to represent the forces acting on the cylinder as it rolls.
bi Show that the linear acceleration of the centre of mass of the cylinder is a=gsin0.
ii Determine the frictional force acting on the cylinder for 0 = 30°.
c Calculate the rate of change of the angular momentum of the cylinder as it rolls
for 0
= 30°.
