FA trolley is pulled in a straight line across a level floor. Figure 1 shows how the pulling force changes with the distance the trolley moves.
Figure: A graph of the pulling force acting on a trolley against the distance the trolley moves
a.[1]
Use Figure to give the pulling force acting on the trolley over the first 6.0 m.
b.[2]
Calculate the work done on the trolley over the first 6.0 m.
c.[2]
Calculate the total work done on the trolley over the whole 10 m.
d.[1]
The trolley is pulled across the same floor throughout. Suggest why the pulling force needed falls after 6.0 m.
