Question

Rita’s bike starts from rest and accelerates at 2.0m/s2. Where will she be relative to her starting point after 7 seconds?

Answer 1

Explanation:

u = 0 m/s

a = 2 m/s^2

t = 7 s

Using 2nd Equation of Motion,

$s = ut + \frac{1}{2} \times a \times {t}^{2}$

$= \frac{1}{2} \times 2 \times 49$

$= 49 \: m$

Therefore, the distance travelled is 49 m.
