2-d kinematic question

  1. Sep 19, 2011 #1
    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.

    Vector approach is suitable for this kind of problem . resolve the velocities and forces and apply newton's eqn of motion and equations of motion in straight line to solve the velocities and position at every time in x and y direction independently!!!
