    2. Relevant equations

    V1-V2=Change in Velocity


    3. The attempt at a solution

    I need to draw the resultant. What next?

    Welcome to the PF. I believe that they want you to calculate the change in vector velocity. So express the entry velocity as a vector in xy coordinates, and the exit velocity in xy coordinates. The difference is just the subtraction of the two vectors, carried out with components.
