Magnitude of Angular Momentum

1. A car of mass 1000 kg moves with a speed of 50 m/s on a circular track of radius 100 m. What is the magnitude of its angular momentum (in kg.m^2/s) relative to the center of the racetrack?

2. A Body oscillates with simple harmonic motion along the x-axis. Its displacement varies with time according to the equation x=5 sin (pie t + pie/3). The velocity (in m/s) of the body at t=1 second is:

Hello and thank you for using Brainmass.

1. The angular momentum is the linear momentum croos-multiplied by the distance vector to the point of refference.

In general, this mean that the magnitude of teh resultant angular momentum is teh multiplication of the magnitudes of ...
