,1. [In this question, position vectors are given relative to a fixed origin.] At time t

seconds, where t > 0 , a particle P has velocity v m s–1 where
1
2
v = 3t i – 6t 2 j

(a) Find the speed of P at time t = 2 seconds.
(2)

(b) Find an expression, in terms of t, i and j, for the acceleration of P at time t seconds,
where t > 0
(2)

At time t = 4 seconds, the position vector of P is (i – 4j) m.

(c) Find the position vector of P at time t = 1 second.
