As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 45.5 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 5.10 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine the following.
a) the acceleration of the salmon
b) the magnitude of the Force F during this intervalThe post Physics: Netwons Laws first appeared on Nursing School Essays.
