Question

A body moves with initial velocity of 2 m/s and uniform acceleration of 3 m/s². Calculate the velocity when it has travelled the distance of 77 m.

Open in App

Solution

Dear Student ,
$N o w, v e l o c i t y v^{2} = u^{2} + 2 f s = 4 + (2 \times 3 \times 77) = 466 \Rightarrow v = \sqrt{466} = 21 \cdot 6 m / s$
