AI Thread Summary
The discussion revolves around calculating the height a pilot can lift a mass using the power generated while pedaling. The pilot averages 190 watts over 25 seconds, and the mass to be lifted is 110 kg. To find the height, the work done by the pilot must first be calculated using the formula W = P x T, which gives a total work of 4750 joules. The force exerted is calculated using F = mg, resulting in 1078 N. The height can then be determined using the rearranged work formula W = mgh, leading to the final calculation of height.

Homework Statement


In 1979 the human powered Gossamer Albatross flew across the English Channel. The pedalling pilot averaged 190 W over the distance. If the pilot's power was used to lift a 110 kg mass, to what height would he lift the mass in a time of 25 s?


Homework Equations


P = W/T
W=FxD


The Attempt at a Solution


All I am looking for is the formula to solve this question.
P = 190 J/S
M = 110 kg
Time = 25 s

How to find the height?

Work = F x D


F=mg
F=110 x 9.8
F=1078 N

But how do we find the distance?
 
190 W is a quantity of power. Check out the definition (and units) of power.
 
Use the power rating to calculate the amount of work that the pilot will do during the stated period of time.
 
Instead of W=FD think about W=mgh

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
