5. The sport of curling is played on ice. The goal is to get your "rock" (a granite puck-shaped object with a mass of 44 lbs) as close to the center target as possible. Imagine you are a master curler, and it is the gold medal game of the Olympics. You need to knock out two of your opponents' rocks in order to win the game, while keeping your rock in the rings. Your goal is to determine with what speed and at what angle must your rock hit the opponent's first rock. The constraints are: (1) your rock must stop when it collides with the second rock, (2) both of your opponent's rocks must leave the rings with a speed of 0.50 m/s.
