. A particle is moving in the i−j plane with an acceleration of (1 −t)i+tj where t is the time. The particle is projected from the origin with an initial velocity of 3 2 i ms−1 . Find the displacement of the particle at time t and the value of t when it is moving in a direction of motion. What is the angle between its velocity and displacement at this time?
