# Help with Physics Problems

1. Jan 20, 2010

I'm having trouble approaching this problem. I'm not sure how to set it up. Any help would be appreciated especially with necessary formulas and equations. Thank you.

A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 7.0 m, y = 9.0 m, and has velocity v = 5.0 m/s + -10.0 m/s . The acceleration is given by the vector a = 7.0 m/s2 + 0 m/s2 .

I need to find the velocity vector at time= 6 seconds and position vector at 4 seconds. Thanks again.
