A body of mass5 kgmoving with a uniform speed32 m s-1inX-Yplane along the liney=x+4. The angular momentum of the particle about the origin will be _______kg m2 s-1.

Answer:
60.00
Solution:

Equation of line given: y-x-4=0.

Let d1 be the perpendicular distance of given line from origin.

d1=-412+12=22

So, |L|=mvd1=5×32×22 kg m2 s-1

=60 kg m2 s-1
