Question

Calculate the potential energy of a simple
pendulum of mass m when it is displaced slightly by x
from the mean position.​

Answer 1

Answer:

At what distance from mean position is its kinetic energy equal to its potential energy. 2- At what points is its speed half the maximum speed. (1) Let x be the distance where KE is equal to PE. kinetic energy equal to its potential energy at x=2

Answer 2

x which is mean position to balanced force is equals to vector quantity 2+x
