Question

A car travels with a uniform velocity of $25m{s}^{-1}$ for $5s$ the brakes are then applied and the car is uniformly retarded and comes to rest in further $10s$ find the distance which the car travels before the brakes are applied.

Answer 1

Given, $Velocity=25m/s,t=5s$

We know that,

$Distance=speed\times time$

$s=25\times 5$

$s=125m$.
