A student rolls a 3 kilogram ball down the same ramp used in Setup 2. The speed of the ball after 2 seconds was 4 meters per second. The student concludes that the kinetic energy of the 3 kilogram ball is identical to the 1 kilogram ball after it has rolled down the ramp for 2 seconds. Explain whether the student's conclusion is correct or incorrect. Use evidence from the investigation to support your answer.
