How to Calculate Work Done by a Force in Space?

AI Thread Summary
To calculate the work done by gravity on a 1250 kg probe in space, focus on the work-energy theorem rather than the specifics of gravitational force. The problem provides sufficient data, including the change in speed from 225 m/s to 227 m/s over a distance of 6750 m. The key is to treat it as a general force acting on the probe, simplifying the calculation. By applying the work-energy theorem, the work done can be determined without needing to calculate gravitational acceleration. This approach streamlines the problem and emphasizes energy changes rather than gravitational specifics.

Homework Statement


The force of gravity acts on a 1250 kg probe in outer space. It accelerates the probe from a speed of 225 m/s to 227 m/s over a distance of 6750 m. How much work does gravity do on the probe?

Iwas wondering how to approach gravity in this problem. Should I assume gravity as its value on Earth or calculate an acceleration for it based on the info given?

Neither. This is a straight up energy question. You even have more data than is required for the problem.

Think about applying the work-energy theorem.
 
Forget that it's gravity …

just read it as "a force acts …" :wink:​

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...
