A car of mass 300 kg is travelling on a circular track of radius 100 m with a constant speed of 60 m/s
Calculate the angular momentum ?

Explanation

`vec(L)=vec(r )xx vec(P)`
`vec(P)=mv`
`= 300xx60`
= 16000 kg m/s (directed along the tangent to the circle)
`vec(L)= rP sin theta, theta = 90^(@)`
`vec(L) = rP`
`= 100xx18000`
`= 18xx10^(5)kg m^(2)s^(-1)`.
