Question

A van starting from rest moves with a uniform acceleration of $0.1m/s^2$ for 2 minutes. Find the speed acquired and the distance travelled?

• A. 12m/s, 760 m
• B. 12m/s, 720 m
• C. 13m/s, 670 m
• D. 14m/s, 700 m

Answer 1

The correct option is B

12m/s, 720 m

Here,

u = 0 , a = $0.1m/s^2$ , t = 120s

Using,

v = u + at

v = 0 + (0.1 x 120)

v = 12 m/s

Also,

S = ut + $\frac{{at}^2}{2}$

= (0 x 120) + $\frac{0.1x120x120}{2}$

S = 720 m
