A particle is moving along a straight line such that square of its position varies with time as shown in the following graph. What is the velocity (m/s) of particle at $x = \frac{1}{6} m$ .

Answer:

Solution:

The graph gives:

$x^{2} = \frac{4}{3} t$

Differentiate with respect to time.

$2 xv = \frac{4}{3}$

$v = \frac{2}{3 x}$

$v_{x = 1/6} = \frac{2}{3 ( 1/6 )} = 4 m/s$
