Car A with a mass of 1250 kg, is traveling at 30 m/s to the east. Car B is a truck with a mass of 2000 kg, traveling to the west at 25 m/s. assume these two vehicles experience an inelastic collision but do not stick together, and car A goes off 10 m/s to the west. what will be the resulting velocity of car B?

2. M1*V1 + M2*V2 = M1*V3 + M2*V4.
1250*30 - 2000*25=-1250*10+2000*V4.
Divide both sides by 100:
12.5*30 - 20*25 = -12.5*10 + 20V4.
375 - 500 = -125 + 20V4.
-125 + 125 = 20V4.
V4 = 0. m/s = Velocity of B.
