Question

A car of mass 1000 kg moves with a speed of 55 m/s on acircular track of radius 120 m. What is the magnitude of itsangular momentum (in kg . m2/s) relative tothe center of the race track? A.) 3.3 x 109 B.) 6.6 x 108 C.) 6.6 x 105 D.) 3.3 x 106 E.) 6.6 x 106 A car of mass 1000 kg moves with a speed of 55 m/s on acircular track of radius 120 m.

Explanation / Answer

Given : .                Mass (m) = 1000 kg .                Velocity (v) = 55 m /s .                Radius (r)   = 120 m . We know that : .                Angular momentum is : L = m v r   = (100 kg * 55 m /s * 120 m ) = 6.6 *106    kg - m2   /s . hope this helps u!
