Question

Ball A was carried to the top of a hill in a straight line, while ball B was carried in a longer, zigzag path. At the top of the hill, both balls were left at rest. A student draws a graph that depicts each ball's final potential energy. Which statement describes the final potential energy of the balls?(1 point)

Both balls have equal potential energy.

Neither ball has any potential energy.

Ball A has more potential energy.

Ball B has more potential energy.

Answer 1

Answer: 1. Both balls have equal potential energy.

2. Potential energy would decrease, while total mechanical energy would remain constant.

3. A slide

4. Mass is eliminated when equating gravitional potential energy with kinetic energy.

5. 1/2 mv^2 = 1/2 kx^2

Explanation:

I did the test by pure guess and failed but oh well, got the answers

Answer 2

The statement that describes the final potential energy of the balls is "Both balls have equal potential energy".

The potential energy of an object increases with increase in height and decreases with decrease in height.

The maximum height traveled both balls is the same, and the time of the motion does not the affect the potential energy.

P.E = mgh

where;

• m is the mass of the balls
• g is acceleration due to gravity
• h is the height of the hill

Thus, we can conclude that both balls have equal potential energy.
