An airplane from rest accelerates on a runway at 5.50 m/s2 for 20.25s until it finally takes off the ground.

Question

What is the distance covered before take off?

Answer 1

d = 0.5a*t^2.

Answer 2

d=(0m/s)(20.25s) + 1/2 (5.50m/s squared)(20.25s)squared
d= 1128m

Answer 3

d=1130m

Answer 4

a car starts from rest and accelerates uniformly over a time of 5.21 s for a distance of 140 m. Determine the acceleration of the car.

Answer 5
