Its an equation used in physics often and that's what's been covered in my class. So it only makes sense to use an equation that uses F=force, m=mass, and a= acceleration. Did you not know what that meant? I figured if someone were to help me with this question they would know what the...
I did... I said I used... F=ma which would be A=f/m for acceleration which I used. So i plugged A= 405N/51kg and got 7.94 which should be the correct way as I've been told. Why am I not getting the right answer with this?
yes, I've been taught briefly how to do this, that's why I'm asking for help. My prof is horrible and I've checked my work multiple times and it only makes sense that the first answer I got is correct. I know the website we have to use has been marking correct answers incorrectly, but I just...
A woman of mass 51 kg is standing in an elevator. If the elevator floor pushes up on her feet with a force of 405 N, what is the acceleration of the elevator?
______m/s2 down
So far I've used the F=ma equations and I've gotten 7.94 m/s which was wrong and then I figured maybe it was negative...
I know how to find the components but the way you just worded all of that has confused me and I have no idea what you're speaking of. I found the horizontal and vertical components but they were wrong and I was told to do it multiple ways, that's why I'm asking those two simple questions now...
ok, so I figured out the speed (part a) and as you already know the distance (part b). part a is 100 m/s and part b is 474.105m. Now to find the horizontal and vertical components of its velocity... how would I find this? I see someone said the speed from part a would be the same as the...
Sorry about that, but I'll include my work below. But yes I don't undestand how part B is right without part A being correct. In order to get B the A component must be right, but the program marked me as incorrect for that.
So for part a I used V-Vo=(VoSin)t-(.5)(g)(t^2) and ended up with...
This figure attached gives the path of a squirrel moving about on level ground, from point A (at time t = 0), to points B (at t = 6.00 min), C (at t = 12.0 min), and finally D (at t = 18.0 min). Both axes are marked in increments of 10.0 m (therefore the diagram is not drawn to scale). Consider...
So I've been working on this problem for ALMOST a week now and I can't get the right answers for parts A and C. Although for some reason by answer for B is correct, which should make part A correct but it doesn't. I basically need a very helpful person to just do the problem for me, since no...
**I've done various steps to theses problems and can't seem to figure them out. If someone can either give me steps how to do them or just work them out for me I'd greatly appreciate it. Thanks!

HELP! I just need the steps to figured out these 3 problem. I have the answes but I can't seem to figure out how to do it and my notes aren't helping. thanks!

I did this problem, yet I found out that its wrong because I didn't plug the correct force in. I have no idea what to do now though. If someone can show me what I did wrong and explain it, I would greatly appreciate that. Thank you!

I understand just about everything relating to forces, but I'm not exactly sure what they mean by "felt"... the video just said it was a feeling of comlex which didn't make much sense to me. Thank you though for replying.
I'm completely clueless with these statements. I watched a video on this, but all it said is that it was "complex" which didn't explain it much. If someone would possibly help me that would be great.. and appreciated! Thank you.
