Can you check my physics homework please?

In summary, the conversation involves a request for someone to check a physics project that includes predicting the time it takes for a ball to go down a slide and finding the coefficient of friction between a person and the slide. The person is unsure if their calculations are correct, specifically regarding the equation ff = fa - fnet and the resulting coefficient of friction of .4. They also mention that the differences in times seem to be significantly larger.

Can you check my physics homework please??

Homework Statement


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.
