Question

A car starts from rest and accelerates uniformly to a speed of 180km/h in 10s, the distance covered by car in this time interval?

Answer 1

u = 0 m/ s
v = 180 km/h = 50 m/s
t = 10s
a = ?
$a = \frac{v - u}{t} \\ a = \frac{50}{10} = 5 \: \frac{m}{ {s}^{2} }$
s = ?
$s = ut + \frac{1}{2} a {t}^{2} \\ s = \frac{5 \times 10 \times 10}{2} \\ s = 250 \: m$
