The figure shows the kinetic energy $K$ of a simple pendulum versus its angle $θ$ from the vertical. The bob has mass 0.2 kg. The length of the pendulum is ( $g = 10$ m/s²):

Options:

Answer:

Solution:

$K_{ma x} = 15$ mJ at $θ = 0$ and $K = 0$ at $θ_{0} = 0.1$ rad. $K_{ma x} = \frac{1}{2} m g l θ_{0}^{2}$ gives $l = \frac{2 \times 0.015}{0.2 \times 10 \times 0.01} = 1.5$ m.
