Share your reasoning for Question #3.

Question 5

5.

Consider two identical spheres sitting in front of identical compressed springs at the base of the ramps shown.
Each spring is initially compressed the same amount.
The ramps have two different angles of incline, but Point B is the same height in both ramps.
The springs are released, and each sphere is still moving when it reaches top of its ramp.
Assume no friction and that the earth, ramp, spring and the ball are all in the system.

Below are two energy bar charts for Case I and Case II.

Are they correct? If so, share your reasoning. If not, state how they should be corrected and your reasoning for that change.
