Calculate the power output of a 1.0 g fly as it walks straight up a window pane at 2.6 cm/s.
I have no idea how to figure out this answer. I've tried using P = Fv but that hasn't worked.
power= mgh/time= mg*v= .001kg*9.8N/kg*.026m/s = xxx watts
To calculate the power output of the fly, we need to use the formula:
Power = Force × Velocity
In this case, the force can be determined using the equation:
Force = Mass × Acceleration
Since the fly is walking straight up, we assume there is no acceleration. Therefore, the force will be equal to the weight of the fly (mg), where m is the mass and g is the acceleration due to gravity (9.8 m/s²).
First, we need to convert the mass of the fly from grams to kilograms. Since 1 gram is equal to 0.001 kilograms, the mass of the fly is 0.001 kg.
Next, we multiply the mass of the fly by the acceleration due to gravity to calculate the force:
Force = 0.001 kg × 9.8 m/s² = 0.0098 N
Now, we can calculate the power using the force and velocity given in the problem:
Power = 0.0098 N × 0.026 m/s = 0.0002548 Watts
Therefore, the power output of the fly is approximately 0.0002548 Watts.
