Question

A racing car has a uniform acceleration of 4m/s^2.What distance will it cover in 10sec after start

Answer 1

Howdy!!

your answer is:--

Given, acceleration a = 4m/s^2
& time t = 10sec

since, car star from rest
so, initial velocity u = 0

now,

→according to formula
$s = ut + \frac{1}{2} a {t}^{2} \\ = > s = 0 \times 10 + \frac{1}{2} \times 4 \times 10 \times 10 \\ = > s = 2 \times 100 = 200meter$

hence, 200 meter distance will it cover in 10sec after start
