Question

If a 3.0-kilogram object moves 10. meters in 2.0 seconds, its average momentum is...

A) 60. kg-m/sec
B) 15 kg-m/sec
C) 10. kg-m/sec
D) 30. kg-m/sec

Answer 1

C is the best thing that can be done with the new system that is the most popular

Answer 2

`p=15(kg* m)/(s)`

Step-by-step explanation:

Given:

mass
`m=3kg`

distance traveled.
`d=10m`

time taken to travel distance
`d`
`t=2 s`

First, we need to compute the average velocity, then we can compute the average momentum:

`v=(d)/(t)\\ \\=(10)/(2)=5m/s`

we can compute the momentum through the formula:

`p=mv=3* 5=15 (kg* m)/(s)`
