AI Thread Summary
To determine the resulting velocity of the astronaut and equipment after firing a 100 N rocket backpack for 2 seconds in space, the astronaut's mass must first be calculated from the weight of 1,960 N using the equation w = mg. Once the mass is known, the acceleration can be found using Newton's second law, F = ma, where the force is the thrust from the rocket backpack. With the acceleration and time provided, the final velocity can be calculated. The key steps involve calculating mass, then acceleration, and finally applying the time to find the resulting velocity.

Homework Statement


On Earth, an astronaut and equipment weight 1,960.0 N. While weightless inspace, the astronaut fires a 100 N rocket backpack for 2.0 s. What is the resulting velocity of the astronauts and equipment?

?

The Attempt at a Solution


t=2.0 s
w=mg


i am super lost...
idk which equation to use :S
i only know of
v=d/t :S
please help... i would truly appreciate it...

You know the weight, so figure the mass.

You know the force, so figure the acceleration. F = M*a after all.

You know the acceleration, you know the time ... you know the answer.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
