Question

calculate the work done in the pushing a cart through a distance of 5 M against the force of friction equal to 250 Newton also state the type of work done

Answer 1

Hey!

_______________________

Force= 250 N
Distance = 5m
Work done= Force× Distance

W= F×s
W= 250×5
W= 1250 J

Work done is 1250 J (joule).
Work done is negative as displacement and force of friction acts on opposite directions.

Hope it helps...!!!

Answer 2

distance=5m
force =250N
angleΦ= 180deg
cos180= -1
therefore,work done= force*distance*cosΦ
work = 250*5*-1
work = -1250 joules
the work done is negative 1250 joules
