In which scenario is the greatest amount of work done on a wagon? a force of 55 n moves it 8 m. a force of 60 n moves it 6 m. a force of 50 n moves it 5 m. a force of 40 n moves it 10 m.

A force of 55 N moves it 8 m.  
Work is defined as force over distance. So simply multiply the force by the distance to determine how much work was performed. So 
A force of 55 N moves it 8 m. 55 N * 8 m = 440 Nm 
A force of 60 N moves it 6 m. 60 N * 6 m = 360 Nm 
A force of 50 N moves it 5 m. 50 N * 5 m = 250 Nm 
A force of 40 N moves it 10 m. 40 N * 10 m = 400 Nm  
So the most work was done with 55N over a distance of 8 m.
