Question

an aeroplane starts from rest with an acceleration of 3m/s ² and takes a run for 35 seconds before taking off. what is the minimum length of runway and with what velocity the plane take off? ​

Answer 1

Answer:

The plane takes off with velocity 105m/s.

Explanation:

a=3m/s^2

t=35s

u=0m/s (since body starts from rest)

v=? (unknown)

a=(v-u)/t

3=(v-0)/35

v=3*35

v=105m/s

speed=distance/time

105=d/35

d=35*105

d=3675m
