Magnitude and direction problem

  1. Oct 1, 2009 #1
    1. The problem statement, all variables and given/known data
    A 1kg object is moving in the x direction at 15.6 m/s. Just 3.4s later, it is moving at 32.4 m/s at 29.1 degrees to the x axis. What are the magnitude and direction of the force applied during this time?


    2. Relevant equations



    3. The attempt at a solution
    I really don't know where to start. Can anyone help by providing an equation and solution?

    The solution will have to come from you. Start by using the given quantities to find the acceleration of the object. Assume that the acceleration is constant. The starting equation is the definition of acceleration in terms of velocity. This is in two dimensions so you have to use x and y components.
