Most gasoline engines in today's automobiles are belt driven. This means that the crankshaft, a rod which rotates and drives the pistons, is timed to the camshaft, the mechanism which actuates the valves, by means of a belt. Starting from rest, assume it takes t=0.0540 sfor a crankshaft with a radius of r1=4.75 cm to reach 1950 rpm. If the belt does not stretch or slip, calculate the angular acceleration α2 of the larger camshaft, which has a radius of r2=9.50 cm, during this time period.
