Question

If a particle of mass m is moving with constant
velocity v parallel to x-axis in x-y plane as shown in
fig. Its angular momentum with respect to origin at
(I =Px mü
any time t will be
y
m
V
b
X
0 (0,0)​

Answer 1

Answer:

The position vector is given as,

r=yj^

The velocity of the body is given as,

v=vi^

The angular momentum is given as,

L=m(r×v)

L=m(yj^×vi^)

L=−myvk^

Thus, the angular momentum with respect to origin is −myvk^.
