Asked by Becca
Two bumper cars engage in a head on collision. Car A, whose mass is 60 kg and traveling to the right, approaches Car B at 10 m/s. Car B, whose mass is 85 kg, approaches Car A with a speed of 5 m/s. After the collision, Car A bounces backward with a speed of 4 m/s. How fast is Car B going after the collision?

conserve momentum.
60(10) + 85(-5) = 60(-4) + 85v
60(10) + 85(-5) = 60(-4) + 85v
