A) Position W
B) Position X
C) Position Y
D) Position Z
Correct Answer: A
Solution :
At position Z the ball has potential energy (energy that an object has due to its position). When it starts rolling down, the potential energy changes into kinetic energy (energy that an object has due to its movement) and at point W, it will have maximum kinetic energy as compared to points Y and X and thus from this position, it will finish rolling with the greatest speed.You need to login to perform this action.
