A wooden ball with a mass of 0.45 kg is at rest when it is tapped by a wooden mallet that applies an average force of 83 N to the ball. After contact with the mallet, the ball moves forward at 1.3 m/s. How long was the mallet in contact with the ball? A 7.0 milliseconds B. 3.7 milliseconds C. 2.4 milliseconds D. 0.59 milliseconds​

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.
