A particle P moves in a straight line so that its velocity, V m/s at time t ≥ 0 seconds t is given by V = 28 + t – 2t2. Find.
a) The time when p is momentarily at rest.
b) The speed of P at the instant when the acceleration of the particles is zero.
c) Given that P passes through the point O of the line when t = 0, find the distance of P from O when P is momentarily
at rest.
