Question

2 1100 kg cars drive east; the first moving at 30 m/s the 2nd at 15 m/s what is the magnitude of the total momentum of the system​

Answer 1

Answer:

49500 kgm/s

Explanation:

Data given;

• First car; Mass = 1100 kg
• Velocity = 30 m/s
• Second car; mass = 1100 kg
• Velocity = 15 m/s

We are required to calculate the total momentum of the system.

• We need to know that momentum is calculated by multiplying the velocity of a body by its mass.
• Therefore;

Momentum of the first car = 1100 kg × 30 m/s

                                           = 33,000 kgm/s

Momentum of the second car = 1100 kg × 15 m/s

                                                  = 16,500 kgm/s

Therefore;

Total momentum = 33,000 kgm/s + 16,500 kgm/s

                             = 49500 kgm/s

Thus, the total momentum of the system is 49500 kgm/s
