Textbook Question
Chapter 8, Problem 76PP
Momentum and the archerfish. Archerfish are tropical fish that hunt by shooting drops of water from their mouths at insects above the water’s surface to knock them into the water, where the fish can eat them. A 65 g fish at rest just on the water’s surface can expel a 0.30 g drop of water in a short burst of 5.0 ms. High-speed measurements show that the water has a speed of 2.5 m/s just after the archerfish expels it.
76. What is the speed of the archerfish immediately after it expels the drop of water?
- A. 0.0025 m/s
- B. 0.012 m/s
- C. 0.75 m/s
- D. 2.5 m/s
