Question

A wagon of mass 500 kg is travelling around a circular path of radius 200 m with study speed of 90 km/h. What is the angular momentum?

Answer 1

`25 × 10^4\ "kg m"^2//"s"`

Explanation:

Speed `"= 90 kmph" = 90 cancel"kmph" × 5/18 "m/s"/cancel"kmph" = "25 m/s"`

Angular momentum `"= mvr = 500 kg × 25 m/s × 200 m = 25" × 10^4\ "kg m"^2//"s"`
