Question

A body which was intially at rest covers a distance of $30 m$ in first 3 seconds. What is the acceleration? [3 MARKS]

Open in App

Solution

Acceleration : 3 Marks

Distance covered is given by:
$s = u t + \frac{a t^{2}}{2}$
where:
$u :$ Initial velocity
$a :$ Acceleration
30 = $0 \times 3 + \frac{9 a}{2}$
Acceleration a = $6.66 m / s^{2}$
