AI Thread Summary
A constant net force of 135N is applied to a 30.2kg probe, resulting in an acceleration of 4.47 m/s². Initially, the probe is at rest, and the distance traveled in 6 seconds needs to be calculated. The incorrect assumption was made by multiplying the acceleration by time, leading to an erroneous distance of 26.82m. The correct formula to use is X = Vot + 0.5(a)(t)², which gives a distance of 80.46m after solving. This method accurately accounts for the probe's initial velocity and acceleration over time.

Calculate distance from force HELP!

In outer space, a constant net force of magnitude 135N is exerted on a 30.2kg probe initially at rest. What acceleration does this force produce? How far does the probe travel in 6.00s

what i have so far is that F=Ma
where the force is 135N=30.2a solve for a and get 4.47m/s.

now this is where i get lost. to find the distance I am assuming that it travles 4.47m/s so the gerneal idea i got was to multiply by 6.00s and get 26.82m. This answer is incorrect anyone have any ideas?
 
Physics news on Phys.org
ok i got it i figured it out
i had to use a seperat equation where X=Vot + .5(a)(t)^2

x=0(6)+ .5(4.47)(6)^2
solve all that for X and i got 80.46 m and this answer is correct.
 
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 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
