Abody starts moving unidirectionally under the influence of a sourceof constant power . Which one of thegraph correctly shows the variation of displacement (s) with time (t) ?

Answer»




Solution :We know, power =work done per second
=increase in KINETIC energy per second = COSTANT
So, velocity of the body INCREASES with time.
Therefore , slope `((ds)/(dt)=V)` of the s-t graph increases with time.
