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.
