The gear A on the drive shaft of the outboard motor has a radius rA = 0.5 in. and the meshed pinion gear B on the propeller shaft has a radius rB = 1.2 in. Determine the angular velocity of the propeller in t = 1.5 s if the drive shaft rotates with an angular acceleration α = (400t3) rad/s2, where t is in seconds. The propeller is originally at rest and the motor frame does not move.
