Mayan kings and many school sports teams are named for the puma, cougar, or mountain lion Felis concolor, the best jumper among animals. It can jump to a height of 13 ft when leaving the ground at an angle of 40.4°. With what speed, in SI units, does it leave the ground to make this leap? (m/s)

The vertical component of Velocity, V sin 40.4, must provide enough kinetic energy to lift the animal by an amount
H = 13 ft (3.96 m) and create the potential energy required for that height.
(1/2) M V^2 sin^2 40.4 = M g H
V^2 = 2 g H/(sin^2 40.4)
Solve for V 
drwlsstop answering questions...you're horrible!
