A racing car has a uniform acceleration of `4 ms^(-2)`. What distance it covers in 10 s after the start ?

Text Solution

Verified by Experts

Given : acceleration = `4ms^(-2)`
time = 10s and initial velocity =0
Formula : `s=ut+1//2 at^2`
distance covered `s=0 xx t + 1//2 xx 4ms^(-2) xx (10s)^2`
`s=1//2xx4 ms^(-2) xx 100 s^2`
=1/2 x 400 m
=200 m
