Kim stands in the backyard and jumps with an initial velocity 5.0m/s at an angle of 44 above the horizontal succeeds in passing through the center of the hoop before returning to the ground. Ifkim moving horizontally hen she goes through the hoop. How high above the ground is the center of hoop?

This question belongs in physics, but I will give an answer this time.

Horizontal and vertical motion can be treated separately in kinematics. The only force in the vertical direction we will assume to come from gravity.
Break up the initial velocity vector into components, and use the equation for the vertical component of the velocity to find the time at the top.
(hint: at the top of the jump, vertical velocity is zero)
once you have the time you can find how high she jumped with one of the kinematic equations for displacement.
