Please hurry, being timed. and no links !!! A ball weighing 10 kg rolls down a frictionless incline with a 50 degree angle to the horizontal. if the balls initial velocity was 0 m/s, how much does the mechanical energy of the system change by the time the ball reaches its destination.
A. increases by 12%
B. increases by 58%
C. decreases by 12%
D. does not change

gravity

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 .
