A whale uses sonar (sound waves) to supplement its eyesight for deep water dives. If the speed of sound in water is approximately 1500 m/s, interpret the following signals (as a whale's brain has evolved to do). You may assume the whale is at rest with respect to the water.

a.) The whale sends out a sound wave, which returns in 0.5 seconds. How far away is the object it bounced off?

____m

b.) This sound wave arrives back with its frequency Doppler shifted upwards by 3%. How fast is this object moving towards the whale?
