    How Does Wave Amplitude Affect Ant Weightlessness on a Tightrope?

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

    How Does Wave Amplitude Affect Ant Weightlessness on a Tightrope?

    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?

    How Does Wave Amplitude Affect Ant Weightlessness on a Tightrope?

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

    How Does Wave Amplitude Affect Ant Weightlessness on a Tightrope?

    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...

    Angular Acceleration. Im totally lost

    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...

    Angular Acceleration. Im totally lost

    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...
