Question 38

A particle P P\,P travels along a straight line. At time t t\,t seconds, t≥0t \geq 0t≥0, after leaving a point O O\,O on the line, the velocity of P P\,P is modelled as v=(16+6t−t2)v = (16 + 6t - t^2)v=(16+6t−t2) m s−1^{-1}−1

a.

Find the magnitude of the acceleration of P P\,P at the instant when P P\,P is at rest.
