This is really annoying me. I can't do the question below, or any like it. I can do collisions, relitive vectors, questions that are supposed to be harder...but when it comes to acceleration and velocity vectors I get stuck!
A particle has an intial veloctiy of i + 2j and is accelerating in the direction i + j. If the magnitude of the acceleration is 5(2^0.5), find the velocity vector and the speed of the particle after 2 seconds.
If anyone can explain how I should go about this kind of question I would be very grateful. I need the A in Jan!
