A force of 825 N is needed to push a car across a lot. Two student push the car 35 m . How much work is done? After a rainstorm, the force needed to push the car doubled because the ground became soft . By what amount does the work done by the students change ?

Seeing that you have already answered your own question in the title do we really need to help ?

Work = Force x Distance

Where distance is measured in meters and force is measured in newtons the units of work become N-m or J (joules)

35 x 825 = work in J

part B---double the Force, double the work
