a 160kg space vehicle is traveling along a straight line at a constant speed of 800. meters per second. the magnitude of the net force on the space vehicle is

F = 0

Explanation:

Newton's Second Law tells us, that the sum of the forces acting on the body is equal to mass by acceleration. If a body moves at constant speed, it is because there is no external force that tends to increase or decrease speed.

That is, when there is constant velocity, acceleration is equal to zero.

F = m*a

where:

m = mass [kg]

a = acceleration [m/s^2]

Now if v = constant, a = 0

F = m * a = m *0 = F = 0

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 .
