A lorry accelerates uniformly in a straight line with acceleration of $4ms^-2$ and covers a distance of 250 m in a time interval of 10 s. How far will it travel in the next 10 s?

650

900

800

250

Correct answer is A

We first find the lorry's initial velocity

a = $4ms^-2$ , s= 250m, t= 10, u=?

⇒ ut + $\frac{1}{2}×4×(10^2) ⇒250= 10u + 200 ⇒ 250-200 = 10u ⇒ 50 = 10u ⇒U =\frac{50}{10}$ = $5ms^-1$

For the next 10s, we set t=20s

= s = (5 × 20) + $\frac{1}{2}×4×{20^2}$

= s = 100 + 800

⇒ 900 m

;Distance covered:900-250 =650m
