 HW Helper P: 1,457 2 can be solved with the equation $$w_f = w_i + \alpha t$$ since the angular acceleration is sustained as long as the engine is firing. The intial angular speed is 20 and the final is 245 rad/s. Once you solved for the time use it in the other equation that will give the angle in radians that it turned through during the burn. Using the radius you can then calculate the total distance covered during this time.
