A woman walks due west on the deck of a ship at 4 mi/h. The ship is moving north at a speed of 18 mi/h. Find the speed and direction of the woman relative to the surface of the water. (Round your a
A high-school pitcher is employing a ballistic pendulum to determine the speed of his fastball. A 3.3-kg lump of clay is suspended from a cord 2.0-m long.
A bat emits a sound whose frequency is 82.8 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 38.7 oC, so the speed of sound is not 343 m/s. Assume that air behav
