Calculating Cat Power: How to Find Horsepower Output

Click For Summary
To calculate the average power output of a cat leaping to a 97.0-cm-high table, the gravitational potential energy (P.E.) is first determined using the formula P.E. = mgh, resulting in 42.777 joules. The average power output during the push-off period of 0.230 seconds is then calculated by dividing the energy by time, yielding 185.987 watts. Converting watts to horsepower involves dividing by 746, resulting in approximately 0.249 horsepower. The calculations demonstrate the relationship between mass, height, and power output in this scenario. This problem illustrates the application of physics equations in real-life situations.

Homework Statement


A 4.50 cat leaps from the floor to the top of a 97.0-cm-high table. If the cat pushes against the floor for 0.230 to accomplish this feat, what was her average power output during the pushoff period? Answer in terms of horsepower.

How much energy did the push give the cat? Do you know the equation for gravitational potential energy?
 
No, I"m not sure what the equation for gravitational potential energy is...
 
nevermind! I figured it out!

P.E. = 9.8(4.5)(.97) = 42.777J

42.777/.23 = 185.987W

& 746W = 1hp

185.987/746 = .249hp
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
