Question

A car is traveling with speed of 60km/ h can break to stop with distance of 50m .what will be the stopping distance of car if it is traveling with a velocity of 120km/ h.

Answer 1

Explanation:

$\frac{s1}{s2} = \frac{ {u1}^{2} }{ {u2}^{2} }$

$\frac{50}{x} = \frac{ {60}^{2} }{ {120}^{2} }$

$x \: = 4 \times 50 = 200m$
