Question

A jet plane starts from rest with an acceleration of 3ms-2 and makes a run for 35s before taking off. What is the minimum length of the runway and what is the velocity of the jet at take off nahi di abhi tak nahi bataya usse​

Answer 1

Acceleration a = 3 m s-²

Time t = 35 s

a = ( v-u )

t

3 m s-² = ( v-u )

35s

v = u + a × t

v = 0 + 3 m s-² × 35 s

v = 105 m s-¹

Distance d = Speed v × Time t

d = 105 m s-¹ × 35 s

d = 3675 m
