Question

A body falls freely from rest.if the velocity acquired is numerically equal to the displacement,then the velocity acquired is

Answer 1

at rest u: 0 bt here given v:s there we know final velocity v:u+at so we get V: s+gt

Answer 2

Answer:

19.6 m/s

Explanation:

Given: v=s, u=0.

V^2=u^2 +2as

V^2=0 +2av

V^2 /v = 2×9.8. (g=9.8m/s^2)

V = 19.6 m/s
