On April 15 1912 the luxury cruise liner titanic sank after running into an iceberg. What was the cruise liners speed when it collided with the iceberg if it has a mass of 4.23 x 10 squared 8 kg ship and a moment of 4.9 x 10 squared 9 kg. m/s

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.
