Homework Help: Can you check my physics homework please?

    Can you check my physics homework please??

    1. The problem statement, all variables and given/known data
    My physics project includes predicting
    (1) the time it takes a ball to go down a slide
    I'm not sure if it's right though.

    (2) finding the coefficient of friction between me and the slide.

    Calculations should be correct for the most part, I'm just not sure if I'm doing stuff right. Particularly, I'm not sure about where it goes ff = fa - fnet because then i found the coefficient to be like .4 and that seems really little considering how the differences in times were a lot more.

    You need to post the actual questions, preferably word-for-word.
