A dolphin jumps with an initial velocity of 13.0m/s at an angle of 41.0 ^\circ above the horizontal. The dolphin passes through the center of a hoop before returning to the water.If the dolphin is moving horizontally when it goes through the hoop, how high above the water is the center of the hoop

Answer 1

consider the vertical velocity

Vf^2=Vi^2+2gh

solve for h. Vf (vertical velocity) is zero.

Answer 2

Your links posted for the Dolphin PDF raredes don't work. I'm currently using an android tablet and I have no way of reading or downloading pdfs (essential for school).I like this browser better than the rest of them, but if it does not support viewing and saving pdfs, then it is borderline useless for what I need it for.
