Momentum and the Bumper--Friday and Monday

Today, you will start by experimenting with the applet found here that focuses on momentum of elastic and inelastic collisions.

Create three systems of inelastic momentum and three collisions of elastic momentum.  In each, please indicate the masses involved before the collision, the masses involved after the collision, and the relative velocities before and after.

Your data should look like this
                                BEFORE                             AFTER                Type of collision: elastic or inelastic
m(wagon1)
v (wagon 1)
m(wagon 2)
v (wagon 2)

Write your six trials down on a sheet of lined paper and hand into the teacher, along with your definitions of elastic and inelastic.

When you get done, set up a logger pro with a cart as indicated in the picture.   Remember, you must design a bumper that is SOFT, MID-RANGE, and HARD.  Test each bumper by pushing the car into the box.  Use the v-t graph and write the speed before collision, the speed after the collision, and the time it took to change direction.  Note the condition of the bumper after the collision, and document with a picture (camera should be on my desk, or take a pic on your cell phone)  Hand the three LoggerPro graphs into the teacher.

Finish Worksheet 1, Unit IX.
