Just after a motorcycle rides off the end of a ramp and launches into the air, its engine is turning counterclockwise at 8325 rev/min. the motorcycle rider forgets to throttle back, so the engine's angular speed increases to 12125 rev/min. as a result, the rest of the motorcycle (including the rider) begins to rotate clockwise about the engine at 4.2 rev/min. calculate the ratio ie/im of the moment of inertia of the engine to the moment of inertia of the rest of the motorcycle (and the rider). ignore torques due to gravity and air resistance.

Explanation:

Given

Initial angular speed of engine()=8325 rpm

Final angular speed of engine()=12125 rpm

Initial angular speed of Motorcycle()=0 rpm

Final angular speed of engine()=4.2 rpm

as there is no external torque therefore angular momentum remains conserved
