Example 3
An ambulance has just passed by your home. You detect that the frequency of
the receding siren is 900.0 Hz. If you know that the frequency of the
ambulance's siren is 950.0 Hz, how fast is the ambulance moving? The
temperature of the air in this case is 5C.&lt;
Example 2
A student of mass 85 kg is on an airplane. The airplane is travelling at a constant
L
65 m/s [Right].~
(a) What is the apparent weight of the student?~
(b) The airplane's engines shut off and the airplane experiences free-fall. What is the
student's apparent weight now?~

Analysis:+
1.
How did the forces of kinetic friction compare for the block with the large
side down versus the small side down? How did the forces of static
friction compare? What can you conclude about the effect of surface
area on friction?~
N t
How did the forces of kinetic friction compare for one block versus two
stacked blocks? How did the forces of static friction compare? What can
you conclude about the effect of mass on friction?-
How did the forces of static friction compare for the two blocks of
identical masses but different materials? How did the forces of kinetic
friction compare? What can you conclude about the effect of materials in
contact on force of friction?-
How did the coefficients of static friction compare in all cases? How did
the coefficients of kinetic friction compare? According to this, on what do
coefficients of friction depend?~
How do the coefficients of static and coefficient compare with each other
and forces of static and kinetic friction compare with each other?~
Conclusion: Make a concise statement that relates directly back to the purpose.+
