Pike Place Market Fish Throwing
Downtown Seattle has a famous fish market at Pike Place where large salmon fish are thrown by one person across an aisle and caught by a second person. Both men are about the same height of 1.83m (6 feet). The height from which the fish is thrown is about the same height at which it is caught (the top of their heads). The distance between the two men is about 4 meters and the time it takes to go from one man to another is about 1 second. Judging from the video, the angle at which the fish is thrown and caught is about 45 degrees. Using the equation delta x= vt (velocity times time) the velocity of 4m/s was found because delta x(4m) and time(1s) were known variables since the angle measurement is 45 degrees, the initial vertical velocity is also 4m/s. To find the height of the fish in the air, the equation final velocity squared (0 squared)=initial vertical velocity squared(4 squared) + 2 times acceleration(-9.81) times delta y(change of height). Solving for delta y equals .815meters. The total height of the fish from the floor 1.83+.815=2.645 meters (8.67 feet). The following drawn picture depicts the journey of the fish in the air shown with vectors to illustrate its velocity.
