Political Science

Source: A textbook

horizontal displacement mg relative to the ground (hom its
launch position to its landing position) is measured. Figure 44%
gives Arm as a function of up Assume the ball lands at approch-
motely its launch height. What are the values of (a) um and (b)
way? The ball' s displacement Aza, relative to the sled can also be
measured. Assume that the sled' s velocity is net changed when
the ball is shet. What is Aza, when v, is (c) 5. mls and (d) 15 mls?

whine of the engine), the time of travel ( mentally counting off
seconds), and the direction of travel (by turns along the -
lar street system). From these clues, you know that you are taken
along the following course: so km/ h for 2. min, tum 900 to the
right, 20 km/ h for 4. min, turn 900 to the right, 20 km/ h for 60 s,
tum 900 to the left, so km/ h for 60 s, tum 900 to the ght, 20 km/ h
for 2. min, tum 900 to the left, so km/ h for 30 s. At that point, (a)
how far are you from your starting point, and (b) in what direction
relative to your initial direction of travel are you?
In Fig. , a radar station detects an airplane approaching -
rectal from the east. At first conservation, the airplane is at distance
360 m hem the station and at angle all = 400 above the heri-
zen. The airplane is tracked through an angular change Ag = 1230
in the vertical east -west plane; its distance is then = 790 m. Find
the (a) magnitude and (b) direction of the airplane' s displacement
during this period.

are its (a) y coordinate and (b) speed?

tions, chunks of solid reck
can be blasted out of the vel-
cane: these projectiles are
called volcanic bombs. Figure shows a mess section of Mt.
Fuji, in Japan. (a) At what initial speed would a bomb have to be
ejected, at angle , = to the horizontal, from the vent at A in
order to fall at the foot of the valcano at B, at vertical distance h =
3. 30 km and horizontal distance d = 9. 40 km? Ignore, fer the me-
ment, the effects of air en the boll's travel. (b) What would be the
time of flight? (c) the effect of the air increase er decrease
