When a particle is at the origin, it has a velocity given by vo = (12i + 15j)ms-1. It has a constant acceleration given by a = (-1.5i + 0.25j) ms-2.
(a)        How long does it take the particle to hit the y-axis?
(b)        At what point does it hit the y-axis?
(c)        What is its velocity at the instant it hits the y-axis?
