A5-gram [g] rubber ball is released from a height of 8 meters [m] above a flat surface on the moon. gravitational acceleration on the moon is 1.62 meters per second squared [m/s2]. assume that no energy is lost from frictional drag. what is the velocity, in units of meters per second [m/s], of the rubber ball the instant before it strikes the flat surface?

The velocity is 5.09 m/s

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
