Agolf ball is hit with an initial velocity of 15 meters per second at an angle of 35 degrees above horizontal. what is the vertical component of the golf ball’s initial velocity ?

8.6 m/s

Explanation:

The components of the initial velocity of the ball can be found by using the equations:

where

is the horizontal component

is the vertical component

v is the magnitude of the velocity

is the angle above the horizontal

Substituting:

v = 15 m/s

We find:

this is poiselle's equation from fluid mechanic in physics. mech eng

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 .
