Suppose a car travels 60 kilometers the first two hours and 15 kilometers the next hour. What is the car's average speed?

i don't know, you need to give me some answers.

explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

if they have a finite resultant

dang that balls went far
