If the swing rotates clockwise (looking from above the table), which direction is the angular velocity of the hanging mass pointing in?
select one:
a. clockwise
b. up
c. down
d. counterclockwise

down

Explanation:

if you move to the right there is mass pushing there is a weight pushing down the force in which it makes it larger

1A: The legs can be a adjusted, as well as the sand can be swapped out. It’s a very good design for running multiple tests.
1B: He could add books or something under the front or back legs in order to increase/decrease the incline, therefore imitating the hypothesis.
1C: He can change out the sand grains to finer ones, or coarser ones, and record his results of each test.
2: If he sets the model at a steep incline and tests it with coarse sand and fine sand, seeing which one makes a narrower, deeper hole.
