Can anyone help me with this question, please? A partical P is initially at the point (2,6) in relation to an origin, O, and is moving with velocity (3i + j) ms-. It has constant acceleration (16i + 24j) ms-. Show that after 2 seconds it is moving directly away from O, and find its speed at that time. I would greatly appreciate any help, also details of how to get the answer would be excellent! Thanks.
