Awater-skier is being pulled by a tow rope attached to a boat. as the driver pushes the throttle forward, the skier accelerates. a 83.0-kg water-skier has an initial speed of 6.0 m/s. later, the speed increases to 12.0 m/s. determine the work done by the net external force acting on the skier.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

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 .

the maxium height is 34m/s
