A 1.2-kilogram block and a 1.8-kilogram block are initially at rest on a frictionless,
horizontal surface. When a compressed spring between the blocks is released, the 1.8kilogram block moves to the right at 2.0 meters per second, as shown.
What is the speed of the 1.2-kilogram block after the spring is released?
Given
Formula

Solution
A 3000-kg truck moving with a velocity of 10 m/s hits a 1000-kg parked car. The
impact causes the 1000-kg car to be set in motion at 15 m/s.
Assuming that momentum is conserved during the collision, determine the velocity
of the truck immediately after the collision.
