A jet needs to reach a takeoff speed of 75.0 m/s. If the runway is 1625 meters long, what minimum acceleration is needed? How much time will it take to reach the takeoff speed

1 answer

the average velocity from zero to 75.0 m/s is ... (0 + 75.0) / 2 = 37.5 m/s

time to traverse the runway is ... 1625 m / 37.5 m/s

acceleration = take off speed / traverse time
