The three objects A B and C are moving as shown in the figure, Assume that Va=12

Question

The three objects A B and C are moving as shown in the figure, Assume that Va=12 m/s Vb=9.80m/s and Vc=4.00

Part C

Find the x component of the net momentum of the particles if we define the system to consist of B and C

Part D

Find the y component of the net momentum of the particles if we define the system to consist of B and C

Part E

Find the x component of the net momentum of the particles if we define the system to consist of all three objects

Part F

Find th ey component of the net momentum of the particles if we define the system to consist of all three objects.

Explanation / Answer

Part C: x momentum of system with B and C= Mb*Vb*cos(60)+ Mc*Vc=6*9.8*0.5+10*(-4)=-10.6 kg.m/s

Part D:

y momentum of system with B and C= Mb*Vb*sin(60)+Mc*0=6*9.8*0.866=50.92 kg.m/s

Part E: x momentum of system with A,B and C= Ma*0+Mb*Vb*cos(60)+ Mc*Vc=6*9.8*0.5+10*(-4)=-10.6 kg.m/s

Part F:

y momentum of system with A,B and C= Ma*Va+Mb*Vb*sin(60)+Mc*0=5*(-12)+6*9.8*0.866=-9.08 kg.m/s
