    Resistance Force: 49 kg Diver Dropping 12 m

    Yes that was a typo, but I don't know the correct answer I have to submit to a website and it only let's me know whether my answer is correct or not and it is telling me that 1153.65 N is not correct. Are there any other approaches to this problem?

    Resistance Force: 49 kg Diver Dropping 12 m

    I don't know if I'm just not doing something right or what it is but, i calculated PE: PE=5768.28 J Then you told me I should plug this in for work: F=5768.28/5 F=1135.65 N unfortunately this is not the correct answer... Any ideas what it could be??

    Resistance Force: 49 kg Diver Dropping 12 m

    So I should find the PE of the diver at 12m? PE=49*12*9.81 PE=5768.28? The question asks to determine the average resistance force exerted on the diver by the water. So I would use W=F*D? How do I put this all together now?

    What is the Work Done by a Baseball on a Catcher's Glove?

    Homework Statement A catcher "gives" with a baseball when catching it. If the baseball exerts a force of 511N on the glove, so that the glove is displaced 12.0 cm, how much work is done by the ball? Homework Equations W=F* \Deltax [b]3. The Attempt at a Solution [/tex] W=511*12.0?
