A 2000 kilogram sports car accelerates at a rate of 30 meters per second squared. The velocity of the car is v= at, where a us acceleration in meters per second squared, and t is time in seconds. The Kinetic energy of the car is me=1/2mv^2

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
