(adsbygoogle = window.adsbygoogle || []).push({}); 1. You drag a(n) 16.9 kg steamer trunk over a

rough surface by a constant force of 177 N

acting at an angle of 34◦ above the horizontal.

You move the trunk over a distance of 59.3 m

in a straight line, and the coefficient of kinetic

friction is 0.186.

The acceleration of gravity is 9.8 m/s2 .How much is the work done on the block by

the net force?

Answer in units of J.

u= coefficiant of finetic friction

@= theta

Fnet= [sqrt (mgsin@^(2)+177^(2))] -uFncos@

W= Fnet (d)

W= ? * (59.3)

I have trouble figuring out how to calculate Fnet.
