Rank the magnitude (absolute value) of the momentum of the following systems from least (1) to most (6)

1. a 100 kg new england patriot running at 8 m/s toward a 120 kg denver bronco running toward the patriot at 7 m/s
2. a 0.300 kg baseball being thrown with a speed of 40 m/s.
3. a 100 kg go-cart moving at a speed of 9 m/s overtaking another 120 kg go-cart moving in the same direction at 8 m/s.
4. a.020kg bullet flying at 1000 m/s.
5.a 1000 kg car moving with a velocity of +20 m/s toward a 10,000 kg truck moving toward the car with a velocity of -2 m/s.
6. a 10 kg baby crawling at 0.25 m/s. 3

The order of the different choices from least (1) to most (6) is as follows:

1  = 5

2 = 6

3 = 2

4 = 4

5 = 1

6 = 3

Explanation:

The total momentum for each system can be expressed as follows:

1) m₁*v₁ +m₂*v₂ = 100kg*8m/s -140kg*7m/s = -40 Kg*m/s

Absolute Value : 40 Kg*m/s

Ranked Nbr. 5.

2) mb*vb = 0.3Kg*40m/s = 12 Kg*m/s

Ranked Nbr. 3

3) m₁*v₁ + m₂*v₂ = 100 kg*9m/s + 120Kg*8m/s = 1,860 Kg*m/s

Ranked Nbr. 6

4) mb*vb = 0.020 kg* 1,000 m/s = 20 kg*m/s

Ranked Nbr. 4

5) mc*vc + mt*vt = 1,000 kg*20 m/s -10,000 kg*2m/s = 0

Ranked Nbr. 1

6) mb*vb = 10 Kg*0.25 m/s = 2.5 Kg*m/s

Ranked Nbr. 2

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
