Question

A body is moved from rest along a straight line by a machine delivering constant power. The ratio of displacement and velocity `(s//v)` varies with time `t` as
A.
B.
C.
D.

Answer 1

Correct Answer - A
`w = Delta K.E rArr Pt = (1)/(2) mv^(2) , v = sqrt((2Pt)/(m))`
`(ds)/(dt) = sqrt((2P)/(m)) t^(1//2)`.
