If an object is dropped from a height, its downward speed theoretically increases linearly over time because the object is subject to the steady pull of gravity. Here are observational data on the speed of a ball dropped from a certain height at time x = 0: Time (seconds) X 0 0.2 0.4 0.6 0.8 Speed (m/sec) Y 0 1.92 3.58 6.01 7.88

I have to be leaving soon. I would love to help you at the moment but I can't. :(

questions #18 #19 we have to apply this formula: \(v(t)=-0.092+9.925\cdot t\) please replace \(t\) with \(0.3\) and subsequently with \(15\)

for question #17 you have to make a diagram, reporting along the x-axis the values of time, and along the y-axis the differences between the corresponding predicted value and the experimental value |dw:1449764840358:dw|

t = 0.3

in order to make the residual plot you have to repeat such computation for all the remaining values of \(t\), namley, for \(t=0,0.4,0.6,0.8\)
