A laser beam on a rotating platform shines on a wall 5 meters away. If the platform spins at 1 rev/min, and the laser initially aiming at the closest point on the wall, how fast is the laser moving along the wall after 10 seconds

f=ma newton's second law 7x8=56n

does anyone know or what?

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 .
