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.

Answers

Answer 1

Answer:

The conclusion is incorrect, according to the text.

Explanation:

the small small that is 1 kilogram must go more fast,because begin with more kinetic energy, and can roll more faster by it's light weight, the 3 kilogram ball must be more late for roll down, because have more potential energy than kenetic energy, so in conclusion the light ball go more fast and have more kenetic energy that the heavy ball.
