oh yea, and i also have the value of for T(period) for each of the masses

Is this how I would determine the force?? A thin, flexible metal plate attached at one end to a platform, as shown above, can be used to measure mass. When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with a period that depends on the mass...

nvm i have it solved lol...uhh how do i delete this??

thanx again! =D

i don't believe i didnt realize that! thanku so much! ...im thinking too much lol

OH! so just divide 8.86s by 10 rite??

in seconds 8.86 seconds would be the average time for 10 vibrations in a simple harmonic motion

o I am sorry i meant how would I go about finding T(period) with given values for time and mass...i forgot to proof read :redface: those are the formulas i keep seeing everywhere for example if i had .10kg and 8.86 seconds for the time to find the period would i do this...

how would i go about finding k with given values for mass and time? i have seen these equations over and over...but i feel like I am missing something very important that i need..please help me T=2π√(m/k)) F=-kx

can somebody please help me? im trying to figure out how to get T(period) with having a mass value and a time value. the only ones i have seen over and over again are T=2π√(m/k)) F=-kx

o yea! that makes sense =) can i get the area by counting the squares so the area under the curve would be 24n x s ? if I was to do it mathematically I am confused as to what equation i should use. would i take the integral of f(t)dt from .010 to 0 ? im pretty rusty on my calculus as well =(

ok so this is what I've done so far... (a) J=FΔt=mΔv=Δp J=(500n x .001s)+(1000n x .002s)+(1500n x .003s)+(2000n x .004)+(2000n x .005)+(2000n x .006)+(1500n x .007)+(1000n x .008)+(500n x .009s)+(0n x .010s) J=60n x s (b) ball Δpb=Δpa FΔtb=FΔta Jb=Δpa Jb=mΔva 60n x s=(5kg)v'...

for part 'e' I am confused as to which formula i am supposed to use! =S:confused::cry:

ORRRR lol for part 'a' would i use: (linear impulse-momentum equation) ΣFΔt=Mv2-Mv1 and in this formula what does M represent? just mass or total mass? or...neither? lol

for part 'b', the change in momentum is also equal tot he impulse right? sooo...would i use the impulse answer i got from part 'a' n set it equal to m1'v1' so i can get the correct velocity for v1'? n then from there use tht answer n substitute it into the whole formula i did previously of m1v1...
