A 0.250 kg cart moving at 0.400 m/s has how much momentum?
|
|
0.1 kg-m/s
|
|
|
1 kg-m/s
|
|
|
10 kg-m/s
|
|
|
100 kg-m/s
|
Explanation:
Detailed explanation-1: -The momentum of cart 1 after the collision is p1f = p1i +p1.
Detailed explanation-2: -A 2 kg cart has a momentum of 16 kg m/s.
Detailed explanation-3: -Momentum (P) is equal to mass (M) times velocity (v).
Detailed explanation-4: -The change in momentum is the difference between the final and initial values of momentum. F net = p t, F net = p t, where Fnet is the net external force, p p is the change in momentum, and t t is the change in time. p = F net t .
