Homework Help: Physics

Posted by Leslie on Thursday, November 8, 2012 at 9:55am.

A particle moves with the acceleration a=2e(^-t)i+5cos(t)j
In the instant when t=0 the particle is at the point r=i-3j with the velocity v=4i-3j. Calculate the velocity and position of the particle at any instant.


I tried doing the problem and ended up just rearranging the formulas and meshing them together, which I know isn't correct. I would really appreciate a walkthrough of how to do this type of problem. Thank you!
