A 4.0-kg object is moving with a speed of 2.0 m/s. A 1.0-kg object is moving with a speed of 4.0 m/s Both objects encounter the same constant braking force, and are brought to rest. Which object travels the greater distance before stopping?a) the 4.0 kg mass. b) the 1.0 kg mass.
c) Both travel the same distance.

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.
