When a rattlesnake strikes, its head accelerates from rest to a speed of 23 m/s in 0.39 seconds. assume for simplicity that the only moving part of the snake is its head of mass 110 g. how much (average) power does the rattlesnake need to accelerate its head that fast

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
