Problem B11:
A ball is thrown from one cliff towards another cliff. The speed of the ball is
n_{1} m/s. The sin of the angle with respect to the horizon is
sin&theta = 3/5. Unfortunately, the ball is not thrown with enough speed to
reach the top of the other cliff, and lands below the level a distance of
n_{3} meters. The two cliffs are a distance of n_{2} meters
apart. Take the acceleration of gravity g = 10 m/s^{2}.
What is n_{3}?
