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 vm s–1 where v = 3t 2i – 6t 1 2 j (a) Find the speed o... f 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. (4) ______________________________________________________________________ [Show More]
