Question

Racing car has uniform acceleration of 8m(s)2 what distance will it cover in 20 sec after the start

Answer 1

Answer:

1600meter

Explanation:

using s=ut+1/2at^2

Answer 2

Distance covered will be 1600 m after 20 sec

Explanation:

Given, uniform acceleration = 8 m s⁻²

time taken = 20 sec

By using the second equation of motion we can calculate the distance covered

$s=ut + \frac{1}{2} at^{2}$

where, s= distance covered

u = initial velocity

a = acceleration

t = time taken

=> as the body starts from any point u = 0

=> $s = 0 * 20 + \frac{1}{2} *8*20^{2}$

=> $s = 0 + 4 * 400$

=> s = 1600 m
