A solid ball, a solid disk, and a hoop, all with the same mass and the same radius, are set rolling without slipping up an incline, all with the same initial linear (translational) speed. Which goes farthest up the incline?a)They all roll to the same heightb)The hoop and the disk roll to the same height, farther thank the ballc)The diskd)The hoope)The ball

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .

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.
