    How high does the ball rebound?

    Thanks for replying but again I ONLY NEED HELP WITH G, which asks how high the ball will rebound. I already have the correct answers for a-f. I only posted the other questions so you guys would know what information I was given. So if you could look under my orignal post at the attempt to solve...

    NEED HELP Rotational dynamics and static equilibrium

    I thought i had figured this problem out torque cat - torque of the board = 0 5.4X-(7*0.42) = 0 X = .544m but this is the wrong answer. I don't know what I am doing wrong!

    Minimum angular velocity formula

    Homework Statement A ride in an amusement park consists of a cylindrical chamber that rotates around a vertical axis as shown in the diagram below. When the angular velocity is sufficiently high, a person leaning against the wall can take his or her feet off the floor and remain "stuck" to the...

    NEED HELP Rotational dynamics and static equilibrium

    Well...The pivot point is the second sawhorse (1.50m from the right). I know I need to find the torque but I am not sure how. To find the torque I know I need to find the mass on the left and right of the second sawhorse but that is where I am confused. For example on the left side the length is...

    NEED HELP Rotational dynamics and static equilibrium

    [/B]1. Homework Statement [/b] A cat walks along a uniform plank that is 4.00 m long and has a mass of 7.00 kg. The plank is supported by two sawhorses, one 0.44 m from the left end of the board and the other 1.58 m from its right end. When the cat nears the right end, the plank just begins to...
