Answer:
(a) They must have same direction
(b) It is not necessary for them to have same magnitudes
Explanation:
(a)
Momentum is a vector quantity. It is the product of mass (scalar) and velocity (vector). Thus, if the direction of velocity is changed, then as a result the direction of momentum will also change or its magnitude or component in the same direction will change. Hence, for the two objects to have same momentum, the directions of their velocities must also be the same.
(b)
Since, the momentum is product of velocity and mass. It is possible that two bodies of different masses with different velocities might have same momentum, provided the direction of their velocities is same.
For example, take a body of mass 4 kg moving with speed 5 m/s. It will have a momentum of 20 N.s. Now, consider another body of mass 2 kg, moving with speed 10 m/s. It will also have a momentum of 20 N.s.
Thus, it is not necessary for two objects to have same magnitude of velocity to have same momentum.
(a) they need to have the same direction
(b) they don't need to possess the same magnitudes
What is Momentum?
(a) Momentum may be a vector quantity. it's the merchandise of mass (scalar) and velocity (vector). Thus, if the direction of velocity is modified, then as a result the direction of momentum also will change or its magnitude or component within the same direction will change. Hence, for the 2 objects to own the same momentum, the directions of their velocities must even be identical.
(b) Since, momentum is the product of velocity and mass. two bodies of various masses with different velocities might need the same momentum, provided the direction of their velocities is the same.
For example, take a body of mass 4 kg moving with a speed of 5 m/s. it'll have a momentum of 20 N.s. Now, consider another body of mass 2 kg, moving with a speed of 10 m/s. it'll even have a momentum of 20 N.s.
Thus, 2 objects don't need to possess the same magnitude of velocity to own the same momentum.
