A football is kicked at ground level with a speed of 17.0 m/s at an angle of 40.0º to the horizontal. How much later does it hit the ground and what is its maximum height?

well...

Explanation: Suppose you walk 18.0 m straight west and then 25.0 m straight north.  Show that the order of addition of three vectors does not affect their sum . launched at ground level with an initial speed of 50.0 m/s at an angle . (b) What is the maximum height reached by the arrow along its .

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 .
