Which one of the following statements is NOT true of a free-falling object? An object in a state of free fall ____.

1 answer:

5 0

Hi! C and D are not the answers, because they do fall downward and with the force of gravity. It does fall with an acceleration of -10 m/s. The object actually falls faster as it gets closer to ground and above 10 m/s, so the speed is not constant. The answer is A.

Can someone please help me with this exercise? I'm having problems with point B.

Step-by-step explanation:

After you find the sums for each set, make a list, counting the number of ways a sum can occur.

You'll notice that for Set A, sums of 5, 6, 7, 8, and 9 all appear 4 times. So they have equal probabilities. In Set B, a sum of 7 appears 6 times. Sums smaller or larger than 7 are less common.

When we look at the data, we see that were more sums of 7 than any other sum. So this data was probably from Set B.
