Question

An aeroplane acceleratesonaccelerates on the the run way at 3.20m/square for 32.8seconds until it finally lifts off the ground.determine the distance travelled before take off

Answer 1

the initial velocity = 0 m /s.

acceleration = 3.20 m / s^2

time = 32.8 s

According to laws of motion.

s = ut + 1/2 at ^2

s = 1/2 at²

s=1/2(3.20)(32.8)²

s= 1721.344 m

the distance traveled before takeoff is 1731.3m
