A body of mass 5 kg moving with a uniform speed 3 2 ms-1 in X-Y plane along the line y=x+4. The angular momentum of the particle about the origin will be kg m2 s-1.
Answer
60
Solution
[figure]
L=mvd, d = perpendicular distance of the line of motion from O
Line: x-y+4=0 d= |4| 12+12=2 2 m
L=5 3 2 2 2=60 kg m2 s-1
Answer: 60
