During takeoff, a plane goes from 0 to 50 m/s in 8s. What is its acceleration? Halos fast is it going after 5 s? How far had it traveled by the time it reaches 50 m/s?

a= 50/8 m/s^2
vf=at=50/8 * 5= 250/8 m/s at t=5sec
time to get to 50m/s
50=50/8*t or t=8 seconds
distance=1/2 a t^2=1/2 50/8 64
distance= 400 m check that.

The answer is actually 200 m because you forgot to divide 400 by 2 from the 1/2.

Thank you for setting up the equation, I'm happy I understood it. Although the final answer was off, it wasn't by much, you forgot to divide to get 200. Very grateful for the way you set it up though.
