Detailed Solution
Download Solution PDFThe 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.
