An object is thrown directly up (positive direction) with a velocity (vo) of 20.0 m/s and do= 0. determine how long it takes to get to the maximum height of 24.0 m.

It takes 2.04s to get to the maximum height

Explanation:

This is a vertical throw problem so it can be  treated as a uniform accelerated rectilinear motion. For computing time we are going to use the formula:

where is the final velocity, is the initial velocity, is the time and, is the gravity.

For solving this kind of problems we need at least three values. The values we have are:

Now:

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

i believe the answer is electric potential.
