An airplane reached its takeoff speed of 50 m/s in 7 seconds. What was its acceleration
To find the acceleration, we can use the following formula:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 0 m/s
Final velocity (v) = 50 m/s
Time (t) = 7 seconds
Acceleration = (50 m/s - 0 m/s) / 7 seconds
Acceleration = 50 m/s / 7 seconds
Acceleration = 7.14 m/s^2
Therefore, the airplane's acceleration was 7.14 m/s^2.
