Question

Starting from rest,an aeroplane takes off after covering 0.7km on the runway.if it takes off at 35 m/ s,calcute the acceleration and time for which it moves on the runway

Answer 1

Answer:

Here,

s = 700 m

u = 0

v = 35 ms-1

We know v2 – u2 = 2as

=> v2 = 2as

=> a = v2/2s

=> a = 352/(2×700) = 0.875 ms-2

Answer 2

Answer:

(a) o.875 ms-², 40s it is a correct answer
