5. Ball #1 is rolled down the steeper side of a hill while ball #2 rolls down the opposite side which is less steep. Both balls roll out onto a flat surface at the same level. Assuming there is no friction, how do the speeds of the balls compare when they reach the flat surface? Start a. Ball #1 has the greater speed. c. The speed will be the same for both balls. d. Not enough information is given. b. Ball #2 has the greater speed.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

be subject to a force andchange its motion

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 .
