Question

A racing car has a uniform acceleration of 4 metre per second square how much distance it cover in 10 seconds after start

Answer 1

Explanation:

given,

$u = 0 \\ a = 4m {s}^{ - 2} \\ t = 10s \\ s = ut + a {t}^{2} \div 2 \\ s = 0(10) + (4) {(10)}^{2} \div 2 \\ s = 4(100) \div 2$

$s = 2(100) \\s = 200m$
