Homework Statement http://imgur.com/AotzH28 Two long, straight conducting wires with linear mass density λ are suspended from cords so that they are each horizontal, parallel to each other, and a distance d apart. The back ends of the wires are connected to each other by a slack,low-resistance...

Homework Statement initial problem: A 228 −Ω resistor and a 586 −Ω resistor are connected in series across a 90.0−V line. A voltmeter connected across the 228 −Ω resistor reads 24.0 V . Find the voltmeter resistance. For Req, i got Req=228R/(2+228), R being the resistance of the voltmeter. But...

I'm a bit unsure about my answers. Help! (posting figure) link: http://imgur.com/whExO3S Homework Statement http://imgur.com/whExO3S Consider the harmonic oscillator composed of a mass and two springs of spring constants k1 and k2 (shown in figure). If the mass, M moves on a friction less...

ok. so, Fx(0)=f[o] Fx=ma a=f[o]/m (let this be the first acceleration, or a[1]) and for t=t[f] Fx(tf)=f[o]+αt[f]+βt[f]^2 Fx=ma a=(f[o]+αt[f]+βt[f]^2)/m (let this be acceleration #2, or a[2]) Δa=a[2]-a[1] Δa=(1/m)(αt[f]+βt[f]^2) So, I integrate Δa with respect to t? but, the boundaries for...

a is not a constant, meaning my answer of v[f] is wrong. I could find dv/dt for t[f], but that would only give me the acceleration at that time. How could I find, then, the final velocity at t[f]?

Homework Statement A point mass,m, is constrained to move in one-dimension and is acted on buy a force that depends on time in the following way: F[x](t)=ƒ[o]+αt+βt^2 where ƒo,α, and β are constants . In terms of the quantities given, answer the following: If the object starts off at rest at...
