1. An automobile with a mass of 1000 kilograms accelerates when the traffic light turns green. If the net force on the car is 4000 Newtons, what is the car's acceleration?
2. A 25 Newton force accelerates a boy in a wheelchair at 0.5 m/s^2. What is the mass of the
boy and the wheelchair? (Hint: Solve Newton's second law for mass m=Fla)

wavelength variability is the right one

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

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 .
