Adog sledding team is composed of a 81.8 kg musher (the person driving the sled), a 21.2 kg sled, and four dogs. assume that each dog's pull is fully transmitted to the sled, applied parallel to the ground, and the sled travels along level ground. how much power does each dog supply to pull the sled and driver system at a constant speed of 9.20 m/s if the coefficient of friction between the sled and the snow is 0.110? the acceleration due to gravity is 9.81 m/s².

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 .

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
