Question: Starting from rest at the same vertical elevation, a cube slides down a frictionless incline and a solid cylinder rolls down a similar incline (

Starting from rest at the same vertical elevation, a cube slides down a frictionless incline and a solid cylinder rolls down a similar incline (same angle) without slipping. (Of course, static friction plays a role in rolling without slipping down an incline and must be present here.) Which one reaches the bottom first?
