(adsbygoogle = window.adsbygoogle || []).push({}); 1. A boy bushes a 10 kg box 3 m slowly up a 30 degree slope. There is a constant 30 N frictional force directed down the slope. What is the minimum work required for the boy to move the box.

2. W(friction)=fR, Wg=mg3sin(theta)

3. The work of friction is -90J. the Wg is -147 J, so the minimum work to move the object should be 147+90=237J
