Question 105

The velocity of a particle after t t\,t seconds is given by v=(6t−t2) m s−1v = (6t - t^2) \text{ m s}^{-1}v=(6t−t2) m s−1. When t=0t = 0t=0 the particle is at the origin OOO.

a.

Find the value of t t\,t when the particle comes to instantaneous rest.

b.

Hence find the distance of the particle from O O\,O when the particle comes to instantaneous rest.
