In a collision between a car of mass 1000 kg and a pickup truck of mass 1600 kg, the truck is initially at rest and the car is moving with a velocity 21 m/s. Immediately after the collision, the car is moving with a velocity 2.0 m/s in the same direction it was initially heading.What is the velocity of the truck immediately after the collision?Give your answer in m/s two three significant digits.
