CE Predict/Explain Figure 33 shows a u-versus-t plot for the hammer dropped by the carpenter in Problem. Notice that the times when the hammer passes the two windows are indicated by shaded areas, (a) Is the area of the shaded region corresponding to window 1 greater them, less than, or equal to the area of the shaded region corresponding to window 2? (b) Choose the best explanation from among the following:

I. The shaded area for window 2 is higher than the. shaded area for window 1.

II. The windows are equally tall.

III. The shaded area for window 1 is wider than the shaded area for window 2.

Problem

A carpenter on the roof of a building accidently dropped her hammer. As the hammer falls it passes two windows of equal height, as shown in Figure. (a) Is the increase in speed of the hammer as it drops past window is greater than, less than, or equal to the increase, in speed as it drops past window 2? (b) Choose the best explanation from among the following:

I. The greater speed at window 2 results in a greater increase in speed.

II. Constant acceleration means the hammer speeds up the same amount for each window.

III. The hammer spends more rime dropping past window 1.
