Homework Statement
A bicyclist rides 7.8 km due east, while the resistive force from the air has a magnitude of 2.4 N and points due west. The rider then turns around and rides 5.3 km due west. The resistive force from the air on the return trip has a magnitude of 4.5 N and point due east.
a) Find the work done by the resistive force during the round trip.
_____ J
b) Based on your answer to part (a), is the resistive force a conservative force?
Yes
No
Homework Equations
W=F*D
The Attempt at a Solution
W1=2.4N*7800M = 18720 J
W2=4.5N*5300M = 23850 J
Total Work = W1+W2 = 42570 J
I know my setup is wrong, can someone give me some hints? Thanks
