Question

A jet plane starts from rest with an acceleration of 3 metre per second square and makes around for 35 seconds before taking off what is the minimum length of runway and what is the velocity of the jet takeoff

Answer 1

Answer:

s=ut+1/2at²

s=0+1/2(3) (35²)

s=1/2×3×1225

s=1/2×3675

s=1837.5m

v=u+at

v=0+35×5

v=105m/s
