40POINTS(science) Calculate the TOTAL mechanical energy of a pendulum (mass 4 kg)
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 given below. Total energy is the sum of gravitational potential energy and
kinetic energy. In this problem, round gravity to: g = 10 m/s?.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
