Q. A bat emits a sound whose frequency is 70.8 kHz. The speed of sound in air at 20oC is 343 m/s. However, the air temperature is 42.2 oC, so the speed of sound is not 343 m/s. suppose that air behaves like an ideal gas, and find the wavelength of the sound.
Q. The height of a helicopter above the ground is given by h = 3.20 t3, where h is in meters and t is in seconds. At t = 1.95s, the helicopter releases a small mailbag. How long after its release does mailbag reach the ground?
A golfer takes two putts to get his ball into the hole once he is on green. The first putt displaces the ball into the ball 6.7 m east, and the second 2.16 m south. What displacement would have been needed to get the ball into the hole on first putt.
