Question 45

A particle moves in a straight line.

At time t t\,t seconds, t≥0t \geq 0t≥0, the velocity of the particle is v=(t3−9t2+24t)v = (t^3 - 9t^2 + 24t)v=(t3−9t2+24t) m s−1^{-1}−1

a.

Find the times at which the acceleration of the particle is zero.

[3]
b.

Find the velocity of the particle at each of these times.
