Solution: A 3.0 kg block moving at 12.0 m/s along a horizontal frictionless surface collides with a 2.0 kg block that is initially at rest. After the collision, the two blocks stick together and then slide up a 53° frictionless inclined plane, as shown in the sketch. Calculate the maximum distance L that the two blocks travel up the incline.
