Explanation / Answer

Part A: Find the x- and y-components of the net momentum of system (a). Assume that v = 43m/s .

px = m*v*cos 60 = 172 kg.m/s
py = m*v*sin 60 = 297.92 kg.m/sec...

Part B: Find the x- and y-components of the net momentum of system (b). Assume that v1 = 2.4m/s and v2 = 3.0m/s .

px = -m*v2 = -6*3= -18 kg.m/sec...
py = m*v1 = 9*2.4 = 21.6 kg.m/sec...
Part C: Find the x- and y-components of the net momentum of system (c). Assume that v1 = 5.6m/s and v2 = 13m/s

px = 8*v2*cos 72 = 32.13 kg.m/sec
py = 8*v2*sin 72 - (6*v1) = 65.3 kg.m/sec

Part D: Find the x- and y-components of the net momentum of system (d). Assume that v1 = 4.2m/s and v2 = 4.2m/s

px = 10*v2*sin 35 - (8*v1*sin 35) = 4.82 kg.m/sec....

py = -10.*v2*cos 35- (8*v1*cos 35) = -61.92 kg.m/sec
