## Question

A body moves in a straight line so that at time $\quantity{t}{sec.}$ its velocity $\quantity{v}{ft./sec.}$ is given by the formula$v= \frac{2t-1}{4(2t+1)}.$

Find:

1. the displacement of the body, measured from its position when $t=0$, at the instant when its velocity is zero;
2. the acceleration of the body at this instant.

[The numerical answer to (i) is required correct to two significant figures.]
