relate sine wt back to lambda? sorry I am posting so muchh I am working this out as i go

w^2= 4(pi)^2*(T/mu) subbing into -g=-Aw^2 Sin wt and rearranging gives: (4(pi)^2*T)/mu*A=g*Sin (wt) How do i relater sin(wt) back into the variables I have?

also just thought v=sqrt(T/mu). is Amax = 4(pi)^2 *v^2*?

Homework Statement A large ant is standing on the middle of a circus tightrope that is stretched with tension T. The rope has mass per unit length mu (no symbl). Wanting to shake the ant off the rope, a tightrope walker moves her foot up and down near the end of the tightrope, generating a...

Well I know the inital velocity is zero (starting from rest) and the time is given. Converting 2 revs to rads is 12.57. So it completes 12.57 rads in 0.570s. I am also aware that ang accel = ang vel/time. I am just going around in circles trying to work it out. I was fairly sure it was wrong to...

Homework Statement A computer disk is turned on starting from rest and has constant anglular acceleration. If it took 0.570s for the drive to make its second complete revolution, how long did it take to make the first complete revolution? Also what is its angular acceleration Homework...
