1. The problem statement, all variables and given/known data Lets say I have a .5kg mass traveling at 1200 m/s in the -x direction with 0 acceleration. The force applied to this mass is (2.3i + .093j)N. I have to find position, velocity, and acceleration at say 1 second after the force is applied. No gravitational force involved. 3. The attempt at a solution F = ma will give me the acceleration. Should I just consider the force applied in the x direction? 2.3 N? I've only dealt with 1-d kinematics to this point...it seems the y force will only come into play for position...I could be wrong though.
