Question

a particle is moving along line y = 4x with a speed 10m/s. if the mass of the particle is 2 kg then it's angular momentum about the point (1,4) is​

Answer 1

Answer:

L=mvr where r=perpendicular distance of velocity from origin.

Since velocity is along line 3x+4y−5=0

Hence,distance from origin(0,0) is r=

∣3×0+4×0−5∣

=1

Hence,L=2×8×1

⟹L=16kgm/s
