Thread: velocity vector

A level maths mechanics:

a particle has an initial velocity of i + 2j and is accelerating in the direction i + j. if the magnitude of the acceleration is 5root2, find the velocity vector and the speed of the particle after 2 seconds

Same idea as your question at http://www.mathhelpforum.com/math-he...n-vectors.html.

a = (5root2) (i + j)/root2 = 5(i + j).

Now do the necessary integrations.
