I just started doing some problems and this basic pm problem is giving me a lot of trouble. If a ball was throwen horizontally with 45.08 m/s, how far would the ball fall vertically by the time it reached home plate, 18.28m away? The initial velocity is 45.08 m/s. Now that is the x and y velocity combined, correct? How do I go about finding the x and y velocity? If I don't need to do it for this particular problem could you explain how to do it anyway and how to solve the problem. I tried using arc-cos to find the initial angle then find the velocities from there but I don't think that's right. Thanks for reading.
