A75-kg sprinter accelerates from rest to a speed of 11.0 m/s in 5.0 a) calculate the mechanical work done by the sprinter during this time. i know w=0.5mv^2 = 4538 j . b)calculate the average power the sprinter must generate. p=w/t= 908w. c) if the sprinter converts food energy to mechanical energy with an efficiency of 25%, at what average rate is he burning calories? .

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

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 .
