B is supposed to be on the right side of the beam, both have equal lengths

A rod of length 57.0 cm and mass 1.40 kg is suspended at each end by a 44.0 cm string. The string on side B is cut. Find the magnitude of the initial acceleration of end B. ____________________ l l l l _l_______________ l_...

Ah of course! Its always the simple things you miss.. Thanks

Would the amplitude equal the max arc length? A = s max = theta max/L = .16 This is wrong as well though..

1. What is the amplitude of the pendulum's motion, in meters? (see attached graph) Given: angular frequency=1.26rad/s 2. T=2pi(L/g)^.5; a=-w^2(x); s(t)=Acos(wt+phase); theta=s/L 3. I almost don't even know how to start.. The confusing part I believe is the graph. The max angle...

Sorry for the columns not being lined up again... I'm new to this site.

Ok.. From the Table and using k=F/x: Force (N) Δl (m) k (N/m) 281 0.10 2810 353 0.15 2353.3 665 0.30 2216.7 977 0.45 2171.1 1049 0.50 2098 Could the variations have something to do with the springs pot. energy? This is a question...

1. To the intelligent mind, need some help with the following: Here is a table of the force applied to a spring and the resulting extension, Δl. Force (N) Δl (m) 281 0.10 353 0.15 665 0.30 977 0.45 1049 0.50Plot a graph of Force vs. Δl. What is the...
