Question

determine the angular momentum of a car of mass 1500kg moving on a circular track of radius 50m with a speed of 40m/s.

Answer 1

speed = 40 m/s
circumference
= 2πr
= 100π
angular displacement
= 40×2π/2500π
= (8/250)π
= (4/125)π radian

angular velocity
= angular displacement/Time
= 4π/125 radian/sec

Angular Momentum
= Mass×angular velocity
= 1500×4π/125
= 48π
= 48×22/7
= 150.85 kg.rad/sec

Answer 2

Answer:

3x10^6

Explanation:

velocity=40m/s

radius=50m

mass=1500kg

angular momentum=MVR

= 1500x50x40

=3x10^6
