Question

A stone of mass 10 kg tied with a string of length 0.5 m is rotated in a vertical circle and Total energy of the highest position

Answer 1

Hey mate!

I'm guessing the answer is 125 units.

This is because, The kinetic energy at the highest position is 1/2 mv^2. and the Potential energy is mgh. Here, h=2×radius

Radius in this case is the length of the string. (Check out the attachment for understanding!)

The kinetic energy becomes, 1/2mv^2= 1/2mgr

The total energy is 5/2mgr = 5/2 × 10 × 10 × 0.5 = 125 units.

I have considered the acceleration due to gravity to be 10m/s^2.

If the answer is correct, please mark me brainliest. It will make my day:))
