Weigh the Barbie, her seat, and the car with its bumpers.
Attach an accelerometer to the Barbie car, with the arrow pointed in the direction of the wall.
Determine mu of your vehicle on the floor. (Hint: we did this yesterday)
Use a kinematic formula (those acceleration formulas) to determine what you think the acceleration should have been when it came off the ramp.
Have your teacher cadet print the graph, and then save the file to the desktop with your group member names.
Draw a free-body diagram show all the forces on the level, including the net direction.
Use your data to figure out which bumper is most effective, and why you believe it to be so.
Repeat with the second bumper.
Take a picture of your seatbelt configuration for Barbie and detail why you think it is worthwhile. Leave the Barbie/seat on the back counter by my desk for Wednesday. Make sure you write your name on the Barbie/seat.
Compile all your information, pictures, and observations into a google document and share with me. We'll use the graphing data tomorrow.
