Equations Of Motion

Question

A car accelerates uniformly from rest at 2 m/s². Distance in 5 s is:

RankGuru · Accepted Answer

Using the equation of motion for uniform acceleration:
$s = u t + \frac{1}{2} a t^2$
Given:
- Initial velocity $u = 0 	ext{ (from rest)}$
- Acceleration $a = 2 	ext{ m/s}^2$
- Time $t = 5 	ext{ s}$
Substituting the values:
$s = (0 	imes 5) + \frac{1}{2} 	imes 2 	imes (5)^2 = 0 + 25 = 25 	ext{ m}$.
