A salmon on Alderaan swims upstream to spawn. They must travel about 3000 kmkm in about 90 days, and in the process each fish must do about 1.7×106J1.7×106J of work.
What is the average speed of the salmon?
What is the average power output of the salmon as it swims upstream?
What average force does the salmon exert as it swims?

2) A person pulls a bucket of water up from a well with a rope. Assume the initial and final speeds of the bucket are zero (v-vr-0), and that the person lifted the bucket a vertical distance h. By looking at energy changes in the bucket-Earth physical system, we can make sense of the force the person must exert to pull the bucket up and the amount of work the person does. a) Think about whether this is an open...

1. In Major League Baseball, a typical fastball is pitched at a speed of about 90 mph, or 40 m/s. The batter can perform the remarkable task of completely reversing the direction of this ball and sending it back at about 105 mph, or 47 m/s. Doing this at just the right millisecond to get the ball to go where the batter wants it to go is such an amazing feat that a Yale physicist once jokingly declared that hitting...

A healthy human body maintains a central core of about 37.0 C (98.6 F) To do so, the body must shed excess thermal energy that is comverted from chemical energy due to metabolic processes. This is especially challenging during vigorous exercise, when the body's care temperature can increase by as much as 6 Cin only 15 min, which can lead to convulsions or even brain damage Energy transfer is the key to maintaining a consistent temperature. We can analyze how...
