The trunk is on a horizontal surface, it is being pulled at an angle of 28.6 above the horizontal.
I am attempting to sum all the work and sum it together. The Wg and Wn are both zero since the trunk is only moving horizontally.
The work of the pull is:
Wpull=Fpullxcosθ
=(90.9N)(22.8m)cos28.6...
Homework Statement
You drag a(n) 15.8 kg steamer trunk over a rough surface by a constant force of 90.9 Nacting at an angle of 28.6? above the horizontal. You move the trunk over a distance of22.8 m in a straight line, and the coefficient ofkinetic friction is 0.18.
