    Finding the tension in a circular pendulum without radius or angle.

    It never even occurred to me that the yoyo was in contact with the grounds. Thanks!

    Finding the tension in a circular pendulum without radius or angle.

    But the mass * gravity comes to weight of 0.3822 Newtons, and the tension is only 0.1615 Newtons.

    Finding the tension in a circular pendulum without radius or angle.

    So T = mω2L... It seems to work, tough I'm still not sure how ω corresponds to 1/s^2. I'm so used to translating it linear units via the radius. And that the force along the hypotenuse is less than its y component... Blowing my mind.

    Finding the tension in a circular pendulum without radius or angle.

    Do you mean mω2Lcosθ ? That still leaves me with an unknown of T and an unknown of θ

    Homework Statement Some kid is playing with a yoyo of mass m. The yoyo string is let out to length L, and is spun in a horizontal circle at a constant rate of ω. The yoyo string makes an angle of θ with the horizontal m = 39 grams = 0.039 kilgrams L = 46cm = 0.46m ω = 3 rads/sec...
