Question

A bus starting from rest moves with a uniform acceleration of $0.1m{s}^{-2}$ for $2minutes$. The distance travelled is:

• A. $720m$
• B. $180m$
• C. $360m$
• D. $900m$

Answer 1

Answer: (A)

$720m$

Given:
Initial speed of bus: $u=0m{s}^{-1}$
$a=0.1m{s}^{-2},t=2min=120s$
Using second equation of motion:

$s=ut+\frac{1}{2}a{t}^2$
$s=0\times 120+\frac{1}{2}\times 0.1\times {120}^2=720m$
