The speed `s` (in meters per second) of a long jumper before jumping can be modeled by the function `s=10.9\sqrt{h}`, where `h` is the maximum height (in meters from the ground) of the jumper.



a. A jumper is running 9.2 meters per second. Estimate the height of the jumper.

b. Suppose the runway and pit are raised on a platform slightly higher than the ground. Describe how the graph of the function will be transformed?
