Time left 1:55:02 Question 8 Car 1 of mass 700 kg is slowly moving along at 0.500 m/s when it is hit from behind by car 2 speeding along at 15.0 m/s. After collision, car 1 has a new Not yet speed of 8.00 m/s in the same direction. Which of the following is the force with which car 2 must have struck car 1, if the collision lasted for 0.932 s? answered Also, knowing that conservation of momentum applies to the situation, what is car 2's speed after the collision (V2/) if it has a mass of 850 kg?
