The distance covered before takeoff can be calculated using the equation:
d = (1/2) * a * t^2
where:
- d is the distance covered
- a is the acceleration (5.50 m/s^2)
- t is the time (20.25 s)
Plugging in the values:
d = (1/2) * 5.50 * (20.25)^2
d = (1/2) * 5.50 * 410.0625
d = 1125.34375
Therefore, the distance covered before takeoff is approximately 1125 meters.
Among the given options, the closest one is 1130, so the answer is 1130.
An airplane from rest accelerates on a runway at 5.50 m/s2 for 20.25 s until it finally takes off the ground. What is the distance covered before takeoff?
