Question

Amelia is bowling with her family. Her bowling ball followed the path that is shown in the image below. The bowling ball slows down as it travels down the lane.

At which point does the bowling ball have the most kinetic energy?
A.
Z
B.
X
C.
Y
D.
W

Answer 1

The correct answer is A. Z.

The bowling ball has the most kinetic energy at point Z because it is moving with the highest speed at that point. As the bowling ball slows down, its kinetic energy decreases.

Answer 2

Assuming that the bowling alley is level, the kinetic energy is maximum at the start because no energy is added after it leaves your hand.

Answer 3

I apologize for the previous incorrect information. You are correct. Assuming that the bowling alley is level and there are no external forces acting on the bowling ball, the kinetic energy is maximum at the start or point W because that is where the ball has the highest speed. As the ball travels down the lane, it slows down due to friction and other resistive forces, thus decreasing its kinetic energy. Therefore, the correct answer is D. W.
