A driver with a mass of 60 kg is driving around a racetrack in uniform circular motion at 60m/s. The radius of the circular racetrack is 100 m. What is the magnitude of the driver'smomentum?

ANSWER:


L=360000(kg\cdot m^2)/(s)

Explanation:

Given:

mass = m = 60 kg

velocity = v = 60 m/s

radius = r = 100 m

The angular momentum is given by the following formula:


L=r\cdot m\cdot v

Replacing:


\begin{gathered} L=60\cdot60\cdot100 \\ L=360000(kg\cdot m^2)/(s) \end{gathered}
