ok, i'll get started on it right away...won't get home off the bus for 2 hours so if you happen to be up check out some of the pending work

Homework Statement Initial mass of the rocket is M = 30 x 10^3 kg, while its initial acceleration a = 3g. The rocket has four nozzles of diameter D = 20 cm each. Burning fuel leaves the nozzle with velocity v = 2.0 km/s having temperature T = 600◦C. Assuming fuel is burned completely and the...

Thanks guys for helping. I really appreciated that.

So now that I have that formula is everything that occurs accounted for? I only needed buoyant force to figure out k and then a derived expression for the period. Should that get me home safe?

F = - (Aρg)y = -ky :Ay is additional water displaced Aρg is mass? So then ω = sqrt (k/m) = sqrt (Aρg/m)...Frequency of oscillation is μ = 1/2pi x sqrt (k/m), so the period is 2pi x sqrt (m/Aρg).. ?? Is this correct so far?

I'm sorry, I haven't taken differential equations yet.

Okay, I have the volume. 4000cm^3...or are you saying that's not the way to do it.

Homework Statement An oak block of ρ = 0.9 g/cm^3 and dimensions V = 10cm x 20cm x 20cm is floating in water of ρ0 = 1 g/cm^3. The block is slightly pushed into water and then released. Determine period, T, of oscillations. Homework Equations I'm not sure how to derive the set up of the...

Homework Statement The steel ball is suspended from the accelerating frame by the two cords A and B. The angles (they are on the inside) are both 60 degrees. Determine the acceleration of the frame which will cause the tension in A to be twice that in B. The acceleration is going to the...
