Q2: To meet design criteria, small ball bearings must bounce through an opening of limited size at the top of their trajectory when rebounding from a heavy plate as shown in Figure 1. Calculate the angle 0 made by the rebound velocity with the horizontal and the velocity v of the balls as they pass through the opening.

Q2: To meet design eriteria, small ball bearings must bounce through an
opening of limited size at the top of their trajectory when rebounding
from a heavy plate as shown in Figure 1. Calculate the angle 0 made
by the rebound velocity with the horizontal and the velocity v of the balls
as they pass through the opening.
