kk, thanks. :)

Homework Statement A mass of 100 g is hanging from a spring and is set into simple harmonic motion. If the period of the pendulum is 0.993 s, what is the spring constant? Homework Equations T=2pi(m/k)1/2 The Attempt at a Solution I just want to make sure its right before I plug...

lol I also tried what I had put before[L=7.52E-2 m^3 / pi*r^2 ] and got the same # lol

Ok Volume of Cylinder = Area * Length Area = pi x r^2 Divide .0453 by 2 to get r Area = pi x (.0453/2)^2=.0016117077 V/A = L 7.52E-2 m^3 / 1.61E-3 = 46.7 m/s EDIT: Thanks for your help. You seemed to sum something up wrong lol I got the right answer. Thanks again.!

Ok, I can imagine the .0453m diameter hole, also the sausge coming out lol Now I'm trying to figure out the length. So I would have Pi x r2 x h = Volume H=L L=7.52E-2 m^3 / pi*r^2 ?

Homework Statement Water runs into a fountain, filling all the pipes, at a steady rate of 7.52×10−2 m^3/s How fast will it shoot out of a hole 4.53cm in diameter? Homework Equations A1V1 = A2V2 The Attempt at a Solution A1V1 = 7.52x10-2 m^3/s = A2V2 Divide by A2, which...

BUMP if anyone can help out.

Homework Statement How long does it take for the hanging mass to fall the same distance 31.5 cm? I don't know how to solve for T with everything I have. Help please. Homework Equations mgh=(1/2)I(2h/tr)2 + (1/2)m(2h/t)2 The Attempt at a Solution Okay, previous questions are[All...

I know how to get the Fg if it was just between m1 and m2 lol Based of an example in my book. But adding in a third unknown mass with distance is throwing me off.

Yea, I'm looking for the acceleration of particle M. The formula for that would be a= F/M I know I'm suppose to get the F and mass of M to get the acceleration.

Ok. But would I still use the 3.176x10^8 that was calculated using m1 and m2? Cause then I would assume I would do Fg = G*M*8.5 / .17^2 Fg = G*M*14.0 / .33^2

Fg = G*m1*m2 / r^2 So I would do (6.673x10^(-11)) * 8.50 * 14.0 / .5^2 = 3.176x10^-8 Which would be Fg of m1m2 right? Would I then proceed to make G*M*(m1+m2) / r^2 and solve for M?

Homework Statement An 8.50kg point mass and a 14.0kg point mass are held in place 50.0cm apart. A particle of mass M is released from a point between the two masses 17.0cm from the 8.50kg mass along the line connecting the two fixed masses. Find the magnitude of the acceleration of the...
