The board is propped up at a 32 degree angle. The ball is about the same height as the edge of the cup. For the cup to land under the ball the cup will have to accelerate faster than g. ASU copyright The cup catches the steel ball. The acceleration of the cup is faster than the ball if cosine theta is greater than the square root of 2/3 which is about 35 degrees. ASU copyright A closer look at the starting position of the steel ball and the cup. ASU copyright The steel ball in the cup. ASU copyright
