Question

Rank in order, from largest to smallest, the magnitudes of the momentum p1x through p5x of the objects presented in (Figure 1). Rank the magnitudes of the momentum from largest to smallest. To rank items as equivalent, overlap them.

Answer 1

The decreasing order of the momenta are b>a=d=e>c.

What is Momentum?

• Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction.
• According to Isaac Newton's second equation of motion, the force acting on the particle equals the time rate of change of momentum.
• According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the result of the force and time (referred to as the impulse) is equal to the change in momentum. On the other hand, a particle's momentum represents the length of time needed for a consistent force to bring it to rest.

Solution: The momentum of all the options are mentioned below according to the formula:

a. p = 20 × 1 = 20gm/s

b. p = 20 × 2 = 40gm/s

c. p =10 × 1 = 10gm/s

d. p = 10 × 2 = 20 gm/s

e. p =200 × 0.1 = 20gm/s
