In this question i is a unit vector in the positive x-direction and j is a unit vector in the positive y-direction. Time is in seconds and distances are in metres. The diagram shows the initial positions and velocities of two particles, A and B, that move in the x-y plane. Particle A starts from the origin O at time t = 0. It moves with constant speed 10 ms⁻¹ in the direction 60° above the x-axis.
