Speed and velocity
by MathsTutor4You Mon Sep 07, 2015 5:17 pm
At time t seconds, where 
, a particle P is moving on a horizontal plane with
acceleration [(3t2– 4t)i + (6t – 5)j] m s–2.
When t = 3 the velocity of P is (11i + 10j) m s–1.
Find
(a) the velocity of P at time t seconds,
(b) the speed of P when it is moving parallel to the vector i.
