Homework Statement
Determine the maximum kinetic energy of a uniform rod of mass 0.5Kg and length 0.75 that has an angular displacement of 5 degrees.
Homework Equations
y = rsin (x) where x is the angular displacement
The Attempt at a Solution
Using conservation of energy ETotal = EMech + EPOTENTIAL
Kinetic energy is at a maximum when all potential energy is converted to kinetic energy
Centre of mass of of physical pendulum is equal to L/2
Therefore max kinetic energy = mg (l/2) sin (x)
= 0.0163417 J
I just have no idea if this is right
