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 = 0.0320 s for a crankshaft with a radius of 71 = 3.75 cm to reach 1350 rpm. If the belt does not stretch or slip, calculate the angular acceleration α2 of the larger camshaft, which has a radius of r2 = 7.50 cm, during this time period. α2 = rad/s²
