Determine the initial velocity with which a soccer player must kick the ball, such that the ball bounces and then achieves maximum height of 2.20 m at pt. c or just passing under the horizontal bar. coefficient of restitution between the ball and the field is e=0.5 .

c

explanation:

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 .
