Aparticlewhosemassis2.03.0m/s along the direction r = i + j . What is its angular momentum (in kg · m2/s) relative to the point (0, 5.0) meters?

Explanation:

In order to calculate the angular momentum of the particle you use the following formula:

      (1)

r is the position vector respect to the point (0 , 5.0), that is:

r = 0m i + 5.0m j    (2)

p is the linear momentum vector and it is given by:

  (3)

the direction of p comes from the fat that the particle is moving along the i + j direction.

Then, you use the results of (2) and (3) in the equation (1) and solve for L:

The angular momentum is -30 kgm^2/s ^k

another example of kinetic energy would be,

kinetic energy   >     moving energy
