EXTRA CREDIT Calculate the TOTAL mechanical energy of a pondulum (mass = 4kg) as it swings
from its highest point to its lowest point. Use your equations for gravitational
potential energy and kinetic energy to determine these values based on the data
givon below. Total energy is the sum of gravitational potontial energy and kinetic
energy. In this problem, round gravity to g=10m/s2
