Part A
A golf ball is thrown straight up from the edge of the
roof of a building. A second golf ball is dropped from
the roof a time of 1.06 s later. You may ignore air
resistance
If the height of the building is 20.3 m, what must the initial speed be of the first ball if both are to hit the ground at the same time?

A skydiver is falling straight down, along the negative y direction. During theinitial part of the fall, her speed increases from 16 m/s to 28 m/s in 1.5 s, as shownin Figure 7a. Later, her parachute opens, and her speed decreases from 48 m/s to26 m/s in 11s, as shown in Figure 7b. In both instances, determine the magnitudeand direction of her average acceleration
