Suppose The Packages Stick Together. What Is Their Common Speed After The Collision?

h=2.8 m-high, frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m, from the bottom of the chute. Suppose the packages stick together. What is their common speed after the collision? (Make sure to include an energy bar chart for this problem.)

Concepts: conservation of mechanical energy and conservation of momentum Assumptions: mechanical energy is conserved, frictionless slope Part 1: Use conservation of mechanical energy to determine the speed of the box m just before it collides with box 2m (draw the energy bar chart) Part 2: Use conservation of momentum for the inelastic collision to find their common speed (giant M1V1 equation, solve for Vf)

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group. The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying partner. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
