A car of mass 800 kg is travelling around a circular path of radius 200 m with a steady speed of 42 km/h. Calculate its angular momentum.

Text Solution

Verified by Experts

We are given: m = 800 kg, r = 200 m .
We know that, v = 42 km/h = `(42 xx1000)/(60xx60)=11.6 ms^(-1)`
Using relation: L = mvr
`L = 800xx11.6xx200 = 1856000 = 1.8xx10^(6) "kg ms"^(2)s^(-1)` .
