Question

An aeroplane has a run of 500 m to take
off from the runway. It starts from rest
and moves with constant acceleration to
cover the runway in 30 sec. What is the
velocity of the aeroplane at the take off ?​

Answer 1

Explanation:

Here the distance, time, initial velocity are given and we have to find the final velocity.

First we have to find acceleration by the formula

s=ut+ 1/2at^2 then we can find the final velocity easily by the formula v=u+at.
