A pendulum bob swings back and forth. Ignore air resistance. At point A, the potential energy is 15 J and the pendulum bob is at a height of 1 meter.
a) What is the mass of the pendulum bob? Show work by typing the equation and plugging in numbers.
b) What is the total mechanical energy of the pendulum? Explain.
c) At which point on the diagram will the maximum kinetic energy occur and what is the maximum kinetic energy of the pendulum? Explain.
d) What is the potential energy at point B and D? The height of the pendulum bob at B and D is 0.5 meters. Show your work by typing the equation and plugging in numbers.
e) At point B and D, what is the relationship between kinetic energy and potential energy? Explain.
f) What is the speed of the pendulum at point C? Show work by typing the equation and plugging in numbers.
