    Hula Hoop Rotational Motion Problem

    Homework Statement In throwing a hulahoop with back spin, you toss the hoop to the right, and it (1) moves right with speed v0, but rotates ccw with speed ω0. At some point, O, (2) it will change direction, and at that point it will start moving to the, left, but still be sliding because it...

    Torque around a curb - bicyle forces problem

    The answer provided gives an arcsin function with just r and h, but I'm going to try it for a bit and see what I can get.

    Torque around a curb - bicyle forces problem

    Oh! I understand. So to figure out the angle, it's probably easier to use geometrical arguments than net torque?

    Torque around a curb - bicyle forces problem

    How do I know that the angle perpendicular is the smallest? Also by FR do you mean the applied force? Sorry! I've been on this problem so long I don't even know what I'm thinking anymore

    Torque around a curb - bicyle forces problem

    Homework Statement A bicycle tire with radius R is attempting to go over a curb of height h. If a force F is applied to the center of the wheel, at an angle θ above the horizontal, what angle results in a force with the smallest magnitude to raise the wheel over the curb? Homework Equations...
