Homework Help: Ball In Cup

  1. Oct 13, 2007 #1
    1. The problem statement, all variables and given/known data
    I have a lab to do in which we have a ramp set up on a table. We are rolling the ball down the ramp, and letting it roll of the table. We have to figure out where to place the cup for the ball to roll into. If we do not get the ball in the cup we fail. How can I do that?

    2. Relevant equations
    All I know is the Initial velocity will be 0, since we are placing the ball at the top of the ramp then letting go. And once the ball rolls of the table, Acceleration is going to be -9.8m/s (squared)

    3. The attempt at a solution
    I would find the measurements of the ramp, the distance from the bottom of the ramp, to the end of the table, and the height of the table itself. Then use equations, but I don't know which ones.
