Question

A car starts from rest and accelerates on a straight horizontal track at $5m/s^2$. Find out the distance travel by the car in $8$ seconds?

• A. $40m$
• B. $60m$
• C. $80m$
• D. $120m$
• E. $160m$

Answer 1

The correct option is E $160m$

Given : $u=0$ m/s $t=8$ s $a=5$ $m/s^2$

Using : $S=ut+\frac{1}{2}a{t}^2$

$\therefore$ $S=0+\frac{1}{2}\times 5\times 8^2=160m$
