Problem: Consider a system consisting of three particles: m1 = 2 kg, v1  < 10, -5, 12 > m/s m2 = 9 kg, v2 <- 14, 3, -3>m/s m3 = 2 kg, v3 <- 23, 37, 20 > m/s What Is the total momentum of this system? ptot = kg m/s 

FREE Expert Solution

Momentum:

p=mv

Ptot = (px, py, pz)

px = m1v1x + m2v2x + m3v3x = (2)(10) + (9)(-14) + (2)(-23) = -152 kg•m/s

Consider a system consisting of three particles: 

m1 = 2 kg, v1  < 10, -5, 12 > m/s 

m= 9 kg, v<- 14, 3, -3>m/s 

m= 2 kg, v<- 23, 37, 20 > m/s 

What Is the total momentum of this system? 

ptot = kg m/s
