A biathlete skis up to the shooting range knowing that a single bullseye will win her the gold medal. She raises her rifle such that it is at the same height as the bullseye a distance R meters away. If the initial velocity of the bullet leaving her rifle is v0, find an expression for the height above the bullseye she must aim in order to hit the bullseye. Solve your equation with the values R = 100 m and v0 = 300 m/s. Hint: you might find using a trig identity helpful.
