A ball is thrown directly upward into the air. The graph below shows the vertical position of the ball
with respect to time.
a. How much time does the ball take to reach its
maximum height?
b. How much time does the ball take to reach
one-half its maximum height?
c. Estimate the slope of Ay/At at t = 0.05 s, t =
0.10 s, t= 0.15 s, and t= 0.20 s. On your paper,
draw a coordinate system with velocity (v) on
the y-axis and time (t) on the x-axis. Plot your
velocity estimates against time.

d. From your graph, determine what the acceler-
ation on the ball is.

Aplane flying horizontally at an altitude of 1 mile and a speed of of 500mih passes directly over a radar station. find the rate at which the distance from the plane to the station is increasing when it is 2mi away from the station.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
