A simple pendulum of length 0.4 m swings with angular amplitude $8^{\circ}$ ( $g = 10$ m/s²). Select the correct statement(s).

Options:(select one or more)

Answer:

A, B, C

Solution:

$T = 2 π 0.4/10 = 2 π /5$ s. At $4^{\circ}$ the bob is moving, so $T_{s t r} = m g cos θ + m v^{2} / l$ . Tangential acceleration is $g sin 4^{\circ}$ .
