calculate the total mechanical energy of a pendulum as it swings from its highest point to its lowest point pendulum mass is 4kg use your equations for gravitational potential energy and kinetic energy to determine these values based on the data given below total energy is the sum of gravitational potential energy and kinetic energy in this problem round gravity to G=10 m/s^2
