Question

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

Answer 6

You will be using the following formula to look at the LSRL:

y = 53.24 + 1.65x




is this right then

Answer 7

ok i see

Answer 8

we have 5

Answer 9

yes

Answer 10

0 0.2 0.4 0.6 0.8 = 2

Answer 11
