Figured it out...

Wait, should I calculate each PE separately and then add them together? Would there be 6 different PEs?

Homework Statement I posted the question on cramster at http://answerboard.cramster.com/physics- ... so you could see the picture. Homework Equations W = qV = kq1q2 / r The Attempt at a Solution I figure out A, B, and C, (which are the x component, y component, and the...

See, this is where I am confused. I just don't know what to do. I thought that since it was circular motion, you would just convert the velocity to circular motion velocity. I am so confused,

So would it just change the equation to 4M/m (sqrt gl) = v^2/r where r is the length of the rod, because that would be the radius... is that right?

Homework Statement A bullet of mass .0179kg (m) and speed v passes completely through a pendulum bob of mass 1.3kg (M). The bullet emerges with a speed of v/2. The pendulum bob is suspended by a stiff rod of length 1.08m (L) and negligible mass. What is the minimum value of v such...

I know you are probably going to be very frustrated with me, but I am completely lost. We have never even worked problems of this caliber before, so I am very confused.

I just pulled out the Wf equation from my book because it was in the same section as springs. I don't know what some of the variables even stand for. For the components of the velocity, do you mean just use kinematics?

Homework Statement I have been trying this question for close to two hours now and have gotten it incorrect three time. I would appreciate any help! The spring has a constant of 30 N/m and the frictional surface is .3 m long with a coefficient of friction μ = 1.02. The 4 kg block...

I figured out my mistake. I forgot that I canceled out my masses and was using the equation h=v^2 / 2gsin...

[SOLVED] Energy Conservation Problem Please HELP!:) Homework Statement A 2.3-kg block slides along a frictionless horizontal surface with a speed of 5.9 m/s After sliding a distance of 6 m, the block makes a smooth transition to a frictionless ramp inclined at an angle of 24o to the...

Nevermind...I figured it out. I was entering in the wrong decimal place. Thanks for all your help though. :)

.123(474)9.8

isn't that what I had been using before though? mus(static) mg= mv^2/s and the m's cancel and you solve for v^2 but I still keep getting it incorrect
