It was once recorded that a jaguar left skid marks that were 290 m in length. assuming that the jaguar skidded to a stop with a constant acceleration of -3.90 90 m/(s^ ^ 2) , determine the speed of the jaguar before it began to skid .

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.

change tension

i think the answer would be reserve.

the answer to this is proletariats.

hope this : )
