P ( t) = ∂ t E ( t) = M 2 t I . Similarly, if the power output of the engine is constant during the acceleration, the power can be obtained by dividing the final rotational energy by the acceleration time and use that to calculate ω ( t), which then yields L ( t) and finally, by differentiation, M ( t).
