An object of mass 2.0 kg starts from rest at the top of a frictionless curved ramp. At the bottom,
it collides with and sticks to another 2.0-kg mass object. Together the objects then cross a small
rough section where there is friction before leaving the edge of the table together.

Presentation instructions:
Write a solution that looks like one of the examples of the book: fully explain your reasoning in
words, show all your computations clearly and correctly written (format). Explain any and all
assumptions that you make as you solve the problem.
