Part A
Find the x component of the net momentum of the particles if we define the system to consist of A and C.
p_ x} = ___________kg * m/s}

Part B
Find the y component of the net momentum of the particles if we define the system to consist of A and C.
p_ y} = ___________ kg * m/s}

Part C
Find the x component of the net momentum of the particles if we define the system to consist of B and C.
p_ x} = ___________kg * m/s}

Part D
Find the y component of the net momentum of the particles if we define the system to consist of B and C.
p_ y} = __________kg * m/s}

Part E
Find the x component of the net momentum of the particles if we define the system to consist of all three objects.
p_ x} = __________kg * m/s}

Part F
Find the y component of the net momentum of the particles if we define the system to consist of all three objects.
p_ y} = ___________kg * m/s}

Explanation / Answer

mc vc = 10 * (-2.60) = -2.60

p_ x} = -2.60 kg * m/s}

Part B
ma va = 5 * -11.8 = -59

p_ y} = -59 kg * m/s}

Part C
mB vB cos60 + mc vc = 6*9.60*0.5 + 10 * (-2.60) = 2.8

p_ x} = 2.8 kg * m/s}

Part D
mB vB sin60 = 6*9.60*0.866025 = 49.88304

p_ y} = 49.9 kg * m/s}

Part E
mB vB cos60 + mc vc = 6*9.60*0.5 + 10 * (-2.60) = 2.8

p_ x} =2.8 kg * m/s}

Part F
mB vB sin60 + ma va = 6*9.60*0.866025 + 5 * (-11.8) = 49.88304 - 59

p_ y} = -9.12 kg * m/s}
