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...
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'...
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...
