... oves from position O to A after n number of rounds. Please calculate the value of the potential energy E that the object I has. Also, take the standard gravity acceleration as g, circumference ratio as π.
Himeji Mizuki’s answer:
Difference in height between OA=n *2 π r*sin 30
As kinetic energy E is equivalent to the lost energy from O to A
E= m * g * (Difference in height between OA)
Thus,
E = π nmgr
