Car A with mass of 1250 kg is traveling at 30 m/s to the east. Car B is a truck with 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?
Use MV+MV =MV+ MV to solve. (1250Kg)(-30m/s) +(2,000Kg)(25m/s) = (1250Kg)(10m/s) +(2,000)(V). Rearrange to solve for V. Remember, you have to change the signs for velocity for objects going east to a negative. If your anser is positive, then it goes at that velocity to the west, if negative it goes at that velocity to the east.
I have the same problem
