part one:
an 18.7 kg block is dragged over a rough, horizontal surface by a constant force of 104 n
acting at an angle of 26.6◦
above the horizontal. the block is displaced 51.9 m, and the
coefficient of kinetic friction is 0.223.
find the work done by the 104 n force. the acceleration of gravity is 9.8 m/s^2.
answer in units of j.

part two:
find the magnitude of the work done by the
force of friction.
answer in units of j.

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 .
