The angular momentum of a 100.0 kg object moving around a 75.0 m circle at a constant speed of 3.90 m/s is
A) 0.0 N
B) 29250 N
C) 761 N
D) 390 N

Question

Quizplus · Accepted Answer

The angular momentum (L) of an object moving in a circle can be calculated using the formula $L = mvr$, where $m$ is the mass of the object, $v$ is its velocity, and $r$ is the radius of the circle. Substituting the given values, $L = 100.0 \, \text{kg} \times 3.90 \, \text{m/s} \times 75.0 \, \text{m} = 29250 \, \text{kg} \cdot \text{m}^2/\text{s}$, which corresponds to the unit of angular momentum, not Newtons (N), indicating a mistake in the units provided in the options.
