Barbie Bungee CRA: A Case Study
On the Barbie Bungee CRA we had to find out how many rubber bands we needed to launch off Ken from the MCLC library balcony without hitting his head on the floor. I think the important information when solving this problem are the numbers because I need the numbers so that I could figure out how many rubber bands I need .What I did first was graph the table on the paper so that I could make a slope triangle to find out my growth and y-intercept to make an equation to see how many rubber bands I need.
First I graphed the table onto my paper because I needed to know my starting point and line of best fit. Then I did a slope triangle because I needed to figure my growth which so the slope triangle was 51/11 and I divided it and got 4.6 to
be my growth. Then I found my starting point which as 15 and with the information I had I made and equation y=4.6x+15.
The answer i got wa 85. I was putting in random numbers and 85 came the closest. I added 85 to my equation so it was y=4.6(85)+15 and I got 406. I would have picked 86-90 but I thought it would probably hit the ground because i felt like the inertia would bring the barbie lower than i wanted it to. Throughout this project i have learned how to make a slope triangle and how to make and equation with the growth and y intercept.
