How would you go about figuring out what distance an object on a frictionless circular track has descended when the velocity of the object is 8 ft/s?

Question

anonymous · Answer

what do you mean "how would you go about"

conservation of energy would be the place to start

anonymous · Answer

says its frictionless , so the change in kinetic energy ( which change its speed ) are due to changes in graviatationl potential energy

anonymous · Answer

Ah, I see it now. Set 1/2v^2=gh, solve for h. Thanks!

anonymous · Answer

Yes, that'd be right, assuming you start from rest.
