Question

A racing car has a uniform acceleration of 40 $m/s^2$.What distance will it cover in 10s after start?

• A. 1200m
• B. 1150m
• C. 1000m
• D. 2000m

Answer 1

The correct option is D

2000m

Here,

u = 0 , a = 40 $m/s^2$ , t =10s

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

S = (0 x t) + $\frac{40\times 10\times 10}{2}$

S = 2000m
