thank you all for you help, I now have some ideas to work with!

Does this then mean that the body would cool at the same rate in both situations since they both have a temperature difference of 50 degrees celsius?

Hey, I'm having problems with this question: According to Newton's law of cooling, what cools faster, a person from 150 degress celsius to 100 degrees celsius or 100 degrees celsius to 50 degrees celsius in a laboratory environment? Why? I' not really sure where to start. I know the...

Thank you everyone for your input

I completely agree with you! I'm a university student taking introductory physics and I've never been really strong with the conceptionalization and the thinking process that goes along with this course. I find memorizing formulas as comforting because I think that I've leaned something when in...

so from the vf^2 = 2ad equation, I can find the height by isolating d getting vf^2/2a But now where I'm confused at with this is how do i find the height if i do not know the final velocity?

the question that i have just states that they wasnt to know what heights the 3 ball bearings should be dropped from so that at impact all 3 have the same velocity. I don't think that it matters whether or not they land at the same time, just the same velocity, or that's what it seems like to me

Homework Statement Consider 3 ball bearings, one with a mass of 8g, one with 16g, and one with 32 g. What heights should the 3 ball bearings be dropped from so that all 3 ball bearings have the same velocity? Homework Equations I think that the relevant equation would be: vf^2= vi^2...

oh wow I'm sorry i didn't mean to put that many up, i don't know what happened

okay, I'm starting to see how it's done and how I've mixed up my FBD. I think I just need to practice some more problems. I rearanged the m1a=usm1g to a=usm1g/m1 i then substituted this value for a into: Fapplied=m2a+usm1g Thanks so much for your help, I really appreciated it! Now...

okay so would this make the horizontal component of the FBD for the board: max=Fapplied,x - Ffriction,x (m1+m2)a=Fapplied,x-usm2g,x a=Fapplied,x-usm2g,x/(m1+m2)
