Can someone please help me?
The brakes of a truck cause it to slow down by applying a retarding force of 2.60 103 N to the truck over a distance of 930 m. What is the magnitude of the work done by this force on the truck?
Is the work positive or negative?
Explain Why?

force*distance=work

isn't force opposite direction than distance?
