Question

An aeroplane starts from rest with an acceleration of 3 ms
and takes a run for 35s before taking off. What is the minimum
length of runway and with what velocity the plane took off? ​

Answer 1

Answer:

HEY BUD !

Explanation:

acceleration = 3m / second ^2

V= ?

U = 0

S = ut + 1/ 2 at^2

S = 0 × 35 +1/2 3 × 35^ 2

S= 1/2 × 3 × 1125

S = 1126.5

So the length of the runway = 1126.5
