Question

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 energy. Which goes farthest up
the incline?

A.the ball
B.the disk
C.the hoop
D.the hoop and the disk roll to the same height, farther
than the ball
E.they all roll to the same height

Answer 1

Answer: E- they all roll to the same height
