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 \( t = 0.0760 \, \text{s} \) for a crankshaft with a radius of \( r_1 = 4.75 \, \text{cm} \) to reach 1350 rpm. If the belt does not stretch or slip, calculate the angular acceleration \( \alpha_2 \) of the larger camshaft, which has a radius of \( r_2 = 9.50 \, \text{cm} \), during this time period.\[ \alpha_2 = \quad \text{rad/s}^2 \]
