Having gained entry into a local aquarium, a bobcat launches himself into projectile motion with a velocity of 12.0 m/s directed 30 degrees above the horizontal. At the instant of his launch, the cat is located 15.0 m above the ground, at a horizontal distance of 12.0 m from a large fish tank, and 6.00 m above the water level in the tank, as shown in the figure below. In order to land in the fish tank, the cat must make it over the top of the near wall of the fish tank, which is located 3.00 m below the level of the cat's launch point. Of course, the cat does not want to "overshoot" the entire 10.0 m wide tank and land on the hard ground on the other side! Treat the cat as a point particle (or a ball which has been thrown).
