please read the instructions carefully and do the work correctly without skipping any questions. Please don't forgot to put the values or answer in the table and answer of the questions.

Purpose:

• To verify Conservation of Momentum in various collisions
• To determine what happens to momentum and kinetic energy for various types of collisions
• To confirm the value for the coefficient of restitution for various types of collisions

Equipment

• PhET interactive

Introduction

we will investigate collisions in terms of Conservation of Momentumand observe the changes in kinetic energy that take place during a collision. Remember, momentum is a vector quantity that depends on mass and velocity:
