A small circular object with mass m and radius r has a moment of inertia given by I = cmr^2. The object rolls without slipping along the track shown in the figure. The track ends with a ramp of height R = 3.0 m that launches the object vertically. The object starts from a height H = 9.0 m. To what maximum height will it rise after leaving the ramp if c = 0.30?

The answer is 7.62 m. How do I get this answer? Thank you in advance.

How much is the ramp's inclination with the horizontal?

It's not given.

Actually since it's shot vertically upwards, the angle should be 90 degrees.

I was able to figure this question out. Thank you for trying to help.
