The figure below shows a diver going through general motion. The diver's center of gravity can be assumed to undergo a projectile motion. Assume that the diver takes off from a diving board such that his center of gravity is a height ho = 11m above the water level and enters the water at a horizontal distance 1 = 4m from the end of the board. If the total time the diver remains in the air is t2 = 2.3s, calculate the speed, vo, and angle of takeoff ,O, of the diver's center of gravity. Also determine the height, hi, the diver reaches at the top of the dive. (Note that tr is NOT half of t2.)

Question
The figure below shows a diver going through general motion. The diver's center of gravity can be
assumed to undergo a projectile motion.
Assume that the diver takes off from a diving board such
that his center of gravity is a height ho = 11m above the water level and enters the water at a
horizontal distance 1 = 4m from the end of the board. If the total time the diver remains in the air is t2
= 2.3s, calculate the speed, vo, and angle of takeoff ,O, of the diver's center of gravity. Also
determine the height, hi, the diver reaches at the top of the dive. (Note that tr is NOT half of t2.)
