Asked by bill lin
a) What is the minimum work needed to push a 900 kg car 410 m up a 17.5° incline with zero friction?
If i know this answer is 1.08e6 what equation should i use for the next part because the one i used was wrong
(b) What is the minimum work needed if the effective coefficient of friction is 0.40?

(b) W = M g H + friction work
= M g X sin17.5 + M g X cos 17.5 * 0.4
X = 410 m
= M g X sin17.5 + M g X cos 17.5 * 0.4
X = 410 m
