Mechanics Question Please

Hey, I'm finding mechanics slightly hard at the moment, please could some one help me with these questions.

8) The initial position of P at t = 0 is (2i + 4j)m. If it has velocity (3i– j)ms-1 find its position after
a. 3 seconds
b. t seconds

9) A bicycle is accelerating constantly. It initially has velocity of 10i ms-1. Ten seconds later its velocity is 6i + 8j ms-1. Find its acceleration.

Thanks for any help :smile:
