Problem:(adsbygoogle = window.adsbygoogle || []).push({});

A particle starts from the origin at t=0 with an initial velocity of 5 m/s along the positive x axis. If the acceleration is -3i + 4.5j m/s^2 determine the velocity and position of the particle at the moment it reaches its maximum x coordinate.

Possible equations:

x= xo + vxo t + .5ax t^2

I guess I'm just confused on how to start. I do not think I plug numbers into an equation yet. Do I need to work with the numbers I have before using an equation?

Thanks for any help
