A car acceleration uniformly from 5 m\s to 13m/s in 4.0s. What is the acceleration of the car

Which car has the most kinetic energy? a. a car of mass 1000 kg with a speed of 3 m/s b. a car of mass 2000 kg with speed 7 m/s c. a car of mass 1000 kg with speed 7 m/s d. a car of mass 2000 kg with speed 3 m/s

What are two different ways you could find the value of a? explain these methods.
