Question

A car initially at rest starts moving with uniform acceleration of $10m{s}^{-2}$ for $10seconds$. What is the total distance covered by the car?

• A. $100m$
• B. $500m$
• C. $200m$
• D. $600m$

Answer 1

The correct option is B $500m$

Given,
initial velocity, $u=0m{s}^{-1}$,
(the car is initially at rest)
time taken, $t=10s$,
acceleration, $a=10m{s}^{-2}$

Let the distance covered be ${}^{\prime }{s}^{\prime }$.

From second equation of motion, $s=ut+\frac{1}{2}a{t}^2$
$s=0\times 10+(\frac{1}{2}\times 10\times {10}^2)=500m$
