Asmall air plane's takeoff speed is 30 m/s. with constant acceleration it takes 150 m of runway to become airbourne. how long does it take to become airbourne?

The plane moves at a constant rate of 30m/s

there are 150m in the runway

150/30 = 5

5 seconds is the time it takes for it to be airborne

hope this helps

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
