the length of a pendulum is 25 cm, and the mass of the bob is 300 g. it is displaced from the equilibrium position and released. at the lowest point of the trajectory the ke of the pendulum is 0.265 j.

a. how fast is the pendulum moving when at the lowest point?

b. from what height (above the lowest point of the trajectory) was it released?

c. what is the total mechanical energy of the pendulum?

d. the pendulum is passing through a point 5 cm above its equilibrium position (its lowest point).
