*Homework schedule is subject to change.

HW 1 A: Say you hail a friend across campus, about 100 yards away

a. When would it take linger, in the dead of winter or in the heat of summer?

b. Using a northern winter temperature of T_w = -20 °F (for Minnesota), and a southern summer temperature of T_s = 110 °F, what would be the time difference?

(be careful of units)

B: Plot v_sound vs. Temperature over the range of temperatures from –20 to 110 °F.

(Note: the book’s equation assumes T is in Celsius, but an equation given in class uses T in Fahrenheit.)
