Problem
In a carnival booth, you win a stuffed giraffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal distance of 2.1 m from this point (the figure A person is tossing a coin into the dish with a velocity of 6.4 meters per second at an angle of 60 degrees above the horizontal. The dish is on a shelf above the point where the quarter leaves the hand. The horizontal distance from this point to the dish is 2.1 meters. The vertical distance between the hand-coin point and the dish is unknown and labeled as “?”.). If you toss the coin with a velocity of 6.4 m/s at an angle of 60 (Pages 75 - 82) above the horizontal, the coin lands in the dish. You can ignore air resistance.
