A. My prediction for the 7 inch ramp was that it would go about 20 feet per every 5 seconds until it reached 40 feet, and then it would start to decrease, but what actually happened was that the timing was right, but the distance that it made would actually be ten feet further to 50 feet. For the 14 inch ramp I predicted it would reach a max height of 55 feet in around 15 seconds, but I was off by 5 feet and it would actually reach 60 in that span, I also predicted that it wouldn't decrease all that quickly, but it decreased at around 5 seconds faster than I guessed. For the 21 inch ramp I figured that the skateboard would sort of go down gradually and take a similar speed the whole time, but what actually happened was that it went to its peak height of 65 feet then took a sharp decrease all the way back down to twenty in only a 35 second span.
b. The zeros are where the start of the ramp is.
c. All the zeros are the same because all the boards start from a stopped position, while all the maximums are different because of the different speeds that they accelerate off the ramp at.
d. the higher the slope of the ramp, the quicker the increase and the decrease would be, for instance the 7 inch ramp never got that much speed going down, so therefore it didn't have as much room to decrease in speed.
