Calculate the work done in pushing a bus through a distance of5m against the force of friction equal to 150n also state the type of work done?



Work done = Force x displacement 
Force = 150 N
Displacement = 5 m

Work done = 150 x 5 = 750 joules 

Here , if the bus moves in the direction of force then the work is positive but if the bus does not move or move in the opposite direction of force then the work done is negative .

Work done = force × displacement
= 5 ×150 =750j
