Chapter 2, Problem 23P
Each of the strobe photographs (a), (b), and (c) in Figure P2.13 was taken of a single disk moving toward the right, which we take as the positive direction. Within each photograph the time interval between images is constant. For each photograph, prepare graphs of x versus t, vx versus t, and ax versus t, vertically aligned with their time axes identical, to show the motion of the disk. You will not be able to place numbers other than zero on the axes, but show the correct shapes for the graph lines.

a. Find the velocity of the proton at time t.
b. Find the acceleration of the proton at time t.
c. At what time t is the proton moving at a rate of 6
inch/s?
d. At what time t is the proton at rest? You may give
your answer either in exact form or rounded to 4
decimal places.
1d. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure.
Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.)

A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then
during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed
for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a
sketch like the figures in Section 1.2 of your textbook, marking dots for the position
along the road every minute.
