    finding the angle of inclination help

    this came in our exams:
    A physics student playing with an air hockey table (a frictionless surface) finds that if she gives the puck a velocity of 4.60m/s along the length (1.75m) of the table at one end, by the time it has reached the other end the puck has drifted 3.60cm to the right but still has a velocity component along the length of 4.60m/s She concludes correctly that the table is not level and correctly calculates its inclination from the above information. What is the angle of inclination?

    helpp i have no idea how to solve this.... part of newton's second law

    Edit
    ohhh i almost forgot that the answers will be given after exams.... so you can do so to not answer this question

    What troubles me about this problem is this: we know that there is an acceleration component in one direction (the direction of the drift), but there may be one in the other as well. The problem as stated isn't specified well enough to solve.

    (Now if we knew what the final velocity component is with respect to the direction of the initial velocity, we could do this.)
