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

i know this: questions #18 #19
we have to apply this formula:
v(t)=−0.092+9.925⋅t
please replace t with 0.3 and subsequently with 15
