Question

Rank in terms of momentum

A. A 10,000 kg train car at rest
B. A 100 kg person running at 5 m/s
C. A 1200 kg car going 15 m/s
D. A 15 kg meteor going at a speed of 1000 m/s

Answer 1

See the explanation below,

Step-by-step explanation:

Momentum is defined as the product of mass by Velocity. In this way, we will replace the following equation in each of the cases.

`P=m*v`

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

A)

`P = 10000*0\\P=0`

B)

`P=100*5\\P=500[kg*m/s]`

C)

`P=1200*15\\P=18000[kg*m/s]`

D)

`P=15*1000\\P=15000[kg*m/s]`

From higher to lower momentum
