a particle starts from the point (0,8) metre and moves with uniform velocity of v= 3i^m/s. What is the angular momentum of the particle after 5s about origin (mass of particle is 1 kg)

The momentum of the particle after 5 sec from origin will be 3i kg-m/s.
Momentum is defined as the product of velocity and the mass. Since the particle is moving with the uniform velocity, therefore the momentum of the particle is calculate as
P=m*v
Plugging the values
P=1*3i
=3i kg-m/s
Here the momentum from origin will not make any difference as the velocity of the particle is uniform. therefore the momentum of the particle is 3i kg-m/s.
skmuthamilan2001:
It is not i vector
It is normal vector to both i and j so it is - k vector
no, it is i vector as the particle is neither moving in y direction, nor in z direction
Its wrong
