You (m = 60 kg) and your friend are trapped out on a very icy (friction-less) lake. You remember your physics lessons and decide to push on each other in order to slide to safety. After you push each other you begin to slide one direction at 2 m/s and your friend slides the opposite direction at 3 m/s. What is the mass of your friend?

i will answer your question if you answer mine

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 .

i already answered it by 34/s

it is b. absorbs thermal energy
