Question

A steel marble rolls off a 1.12 m tall table with an initial horizontal velocity of 1.44 m/s. The ball must land in a paper cup that is 0.10 m tall with a diameter of 0.05 m. How far horizontally from the edge of the table should the center of the cup be placed?

Answer 1

how long does it take to fall 1.12-0.1 = 1.1 meters?
4.9t^2 = 1.1
t = 0.474 seconds
how far does it travel horizontally?
1.44 * 0.474 = 0.682 meters

I hope the cup is anchored to the floor ...
