Dolphin echolocation is similar to ultrasound. Reflected sound waves
allow a dolphin to form an image of the object that reflected the waves.
Dolphins can produce sound waves with frequencies ranging from
0.25 kHz to 220 kHz, but only those at the upper end of this spectrum
are used in echolocation. Explain why high-frequency waves work better
than low-frequency waves.

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?
