Question

A racing bike has an uniform acceleration of 4 $m/s^2$. What distance will it cover in 20 s after start ?

• A. 400m
• B. 1600m
• C. 800m
• D. 1200m

Answer 1

The correct option is C

800m

Here,

u = 0 , a = 4$m/s^2$ , t = 20s

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

S = (0 x 20) + $\frac{4x20x20}{2}$

S = 800m

Therefore,Distance covered is 800m.
