Question

A particle moves in a straight line so that x =√t then its velocity is proportional to

Answer 1

Answer:

We can write velocity as dx/dt

Given that

x = √t

Differentiating both sides with respect to time

dx/dt = d√t/dt

Using power rule of differentiation

v = 1/2√t (dx/dt is velocity)

Therefore we can conclude that

V is proportional to 1/√t
