Question

A car, initially at rest, accelerates uniformly at $4m/s^2$ along a straight line. Calculate the distance travelled by car in $6s$?

• A. $24m$
• B. $48m$
• C. $64m$
• D. $72m$
• E. $144m$

Answer 1

Answer: (D)

$72m$

Given : $u=0$ $a=4m/s^2$ $t=6$ s

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

$\therefore$ Distance traveled in 6 s, $S=0+\frac{1}{2}\times 4\times 6^2=72$ m
