The distance (s) travelled by a body in ...

The distance (s) travelled by a body in time (t) is given by `s = ut + (1)/(2)at^(2)`.
How is the formula modified when
(i) body starts from rest , (ii) motion of body is uniform.

Text Solution

Verified by Experts

(i) When body starts from rest, `u = 0`
`:. s = 0 xx t + (1)/(2)at^(2) = (1)/(2)at^(2)`
(ii) When motion of body is uniform, `a = 0`
`:. s = ut`
