    Torque; where to place axis (levers) question.

    This problem involves torque, and levers. I am so stuck on this, I really have no idea where to even begin. The problem states: "Tom weighs 150lb and he wants to lift a 600lb stone lid form a well. We give him a 12ft, unbreakable lever that has one end attached to the stone (at the COM), and...

    Force applied to glove catching a 0.5 kg baseball at 35 m/s

    Trouble with question -- Catching a baseball & momentum There are three parts to this question, and I am stuck on the last part. The question reads as follows: a) A pitched ball with a mass of 0.5kg reaches a catchers glove traveling at 35m/s. How much momentum does the ball have...

    Skier on 27° slope with headwind and friction forces

    This was given to use by our teacher to help us with this last problem: Maintain Downhill F = Downhill F (comp. wgt + comp. F poles) – Wind – Friction (uD * (comp. wgt – comp. F poles)) The X's in the equation that I posted in post two represent the component F of the poles. I have a free...

    Skier on 27° slope with headwind and friction forces

    I just came up with this: 264.4N = (347.4N + Cos(45)(x)N)-8N-(.13(681.8N - Sin(45)(x)N)) The X's in parenthesis after the Cos and Sin represent numbers, but I can't figure out which numbers go into these slots...does anybody have any idea?

    Skier on 27° slope with headwind and friction forces

    [b]1. The problem statement: Slick is skiing down a 27 degree slope (above horizontal) into a headwind (parallel to the slope) of 8N. His mass is 78Kg. The coefficient of friction between the snow and the skis is 0.11. What is the resultant force? If the coefficient of friction...
