Assignment #12 – Chapter 27 Problems

Chapter 27

1*, 4, 7, 8, 12, 15, 16, 20, 21, 28, 31, 36

Due Monday

For problem 1, modify it so that the sound appears to be traveling at 335 m/s and 355 m/s.  The numbers listed seem fishy though.

One source stated Usain Bolt’s top speed was 43.93 km/h ( 27.3 mph) in m/s is 12.2 m/s.

I used 12 m/s as an approximation for his max speed.

If you used the numbers listed in the book…… you would get a speed that seems unreasonable to me.

Speak Your Mind
