Suppose you hear a car approaching and its horn is heard as a 3037. Hz tone. After passing, you hear 2430. Hz.
 
  (a) What was the Mach number of the car?
  (b) What is the speed of sound if the outside temperature is 19.C?
  (c) How fast was the car moving, in meters per second?

Question 2

A 12000-N car is raised using a hydraulic lift, which consists of a U-tube with arms of unequal areas, filled with oil with a density of 800kg/m3 and capped at both ends with tight-fitting pistons.
 
  The wider arm of the U-tube has a radius of 18.0 cm and the narrower arm has a radius of 5.00 cm. The car rests on the piston on the wider arm of the U-tube. The pistons are initially at the same level. What is the force that must be applied to the smaller piston in order to lift the car after it has been raised 1.20 m? For purposes of this problem, neglect the weight of the pistons.
  A) 0.954 kN
  B) 1.88 kN
  C) 1.96 kN
  D) 3.67 kN
  E) 1.20 kN
