what a dumb bear... Anyways, I broke the componets into x and y directions. The y dir. is Tcos(theta) -mg =0 due to their being no motion. also, their are 3 masses. bear, basket, and beam.

is the beam supported by a horizontal string on each end?

I see. T1 = T2(.49) T2 = 21.74lb + T1(.54) I divided .92 into lbs., think you can do that. now ill put T2 in the T1 eq. Right?

Do you mean this: I'll take the x eq. and solve for t1. I get T1 = T2cos(65) / cos (30) now I can take this eq. for T1 and plug it in for T1 in the y eq?

right. I am missing -w. Sorry about the mistake. Now what of the T that I need to solve for. I have Solved for the T in my x and y equation and get bad nasty answers.

Homework Statement I have done all the physics for this problem which I'll detail below. I am only having trouble in doing the simple math to single out the t1 or t2. A mass is hanging from a ceiling. It is supported by two strings which both are attached above to the ceiling. String 1 is...

no. I think you are confusing x0 with x1. the order goes: x0 x1 x2...

my full answer is 1.604938639 when pluging the answers back into the equation and dividing by the derrivative, I only was tacking my answer to 3 decimal places keeping in mind to round up the 3rd decimal place. the choices are 1.600 and 1.604

Homework Statement Use Newton's method to estimate the requested solution of the equation. Start with given value of x0 and give x2 as the estimated solution. Homework Equations x0 = 2 ( this is the first guess numb. you start with) the equation you use is... x = x(guuess #) -...

answer - 8.89m/s...Is this right?

Read my first post. This is a problem I am putting together(it is not homework) and need help only on deciding if I need to include a differential equation. If I do, then what kind? I have never taken a class on D.E's, so need help narrowing down what type. The problem is conservation of...

This site is great, but I have never studied Diff. Eq. and need to know what section I need to look at in order to solve the problem. I need to understand, not copy and past.

Here is the problem. The only help I need with this is to determine the SPECIFIC type of defferential equations to use. (if any at all) i.e, 1st ODE's, ect. A rocket starts from rest on a ramp. Its propellant is consumed at a constant rate for a certain time. The propellent burns out...

That answers my question. Thank you.

This is not a problem that I need help solving, only, I need help determinging if I MUST use an integral, physics problems are two parts right, physics part, then math. Well I need help on the math. it seems as if I should be able to use derivatives only for Newtons 2nd law.
