Homework Statement Tarzan and Jane, whose total mass is 130.0 kg, start their swing on a 5.0 m long vine when the vine is at an angle of 30 degrees with the horizontal. At the bottom of the arc, Jane, whose mass is 50.0 kg, releases the vine. What is the maximum height at which Tarzan can...

a=vt^2/r

i only have omega and the acceleration of gravity

but i don't know the radius of the smaller circle

how do i find v for the smaller radius? isn't the equation Vt=r(omega)?

for the second part of the question, I'm thinking it has to do with omega being the same for both radii? but how can you find r using accel. and omega?

ohh hahaha ok

hmm. what are the units on the period? radians?

what formula is that?

[SOLVED] Centripetal Acceleration, etc. Homework Statement A space station is being built for astronauts to begin training for colonizing other planets. The rate of rotation is chosen so that the outer ring (r=2150m) simulates the acceleration of gravity on the surface of Venus (8.62m/s^2)...

So how should my equation be set up? Fc = Fnsin(theta)?

[SOLVED] Banking Angle, Normal/Centripetal Force? Homework Statement Curves are often banked on highways so that the horizontal component of the normal force provides the required centripetal force. What is the proper banking angle of a 1200 kg car making a turn of a radius of 30 m at a...

[SOLVED] Centrifuge Revolutions? Homework Statement A centrifuge accelerate from rest to 15,000 rpm in 240s. Through how many revolutions did it turn in this time? Homework Equations am i approaching this problem correctly? The Attempt at a Solution 15000rev/m (1m/60s) (240s) =...

yep! thanks so much!

OK! i did this and got each rope had 113.28 N of tension.
