What angle does the pendulum swing on the other side after being pulled 22 degrees to one side and then released, with a 420 g ball tied to a 42-cm-long string?

Options:
a) 22 degrees
b) 44 degrees
c) 66 degrees
d) 88 degrees

Answer :

Final answer:

Upon release from a 22-degree angle, a pendulum will swing back to the other side to an angle of approximately 22 degrees, assuming there are negligible losses to friction and air resistance.

Explanation:

The concept of conservation of energy in a pendulum's motion. When a pendulum swings to one side and is released, it will swing back to approximately the same angle on the opposite side, assuming that there is no energy loss to friction or air resistance.

In this case, if you pull a pendulum to a 22-degree angle and release it, it will swing back to the other side to an angle that is very close to 22 degrees.

Upon release from a 22-degree angle, a pendulum will swing back to the other side to an angle of approximately 22 degrees, assuming there are negligible losses to friction and air resistance.
