Answer 1

The correct answer is 392 kg-m/s.Key Points

The momentum of a particle is a measure of the time required for a constant force to bring it to rest.
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
- Momentum = Mass * Velocity
In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as p = m • v.
Momentum is a vector quantity; i.e., it has both magnitude and direction.

Additional Information

Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
Conservation of momentum can be described by P1 (before) + P2 (before) = P1 (after) + P2 (after).
Some of the examples of momentum include -
- A train moving at 100 km/h.
- A bullet fired from a gun.
- A baseball flying through the air.
