Study of velocity and kinetic energy, a cart was tested in 9 different trials. The cart carried different masses down 3 different inclinations. Table I shows the mass carried by the cart, the height from which it was released.And that is rolled to get to the end of the ramp. The table also lists the speed and kinetic energy of the cart released the of the ramp.Which of the following variables was a content in Trials 2 and 5?
Correct answer: B. Mass
- A. Height
- B. Mass
- C. Speed
- D. Kinetic energy
Explanation
The correct answer is Mass. In Trials 2 and 5, the mass carried by the cart remained the same, indicating that mass was a constant variable across those trials. This consistency allows us to determine that Mass was a content in Trials 2 and 5. The other variables like Height, Speed, and Kinetic energy varied across the trials, making them incorrect answers.
