A6,0 kg box is at rest on a table. the static friction coefficient u, between the box and table is 0.40, and
the kinetic friction coefficient pen is 0.20. then, a 30 n horizontal force is applied to the box,

Believe and you will succeed

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
