Car A, with a mass of 1250 kg, is traveling at 30 m/s to the east. A truck with mass of 2000 kg, traveling to the west at 25 m/s. An inelastic collision occurred, not sticking together, the car goes off 10 m/s to the west. What is the resulting velocity of the truck?

  • computer programing - ,

    McVv+MtVt must remain unchanged before and after the collision, so

    (1250)(30)+(2000)(-25) = 1250(-10)+2000v
    v=0

    so, the truck comes to a stop and knocks the car backwards.
