A block of mass m travels with speed v0 to the right on a horizontal surface with negligible friction toward a sphere of mass 2m hanging at rest from a light cord, as shown above. The block collides elastically with the sphere. Which of the following correctly describes the speed and direction of the block and the speed of the sphere a short time after the collision? Group of answer choices block: v0/3 to the left, sphere: slightly less than 2 v0/3 block: v0/3 to the right, sphere: slightly less than 2 v0/3 block: v0 to the left, sphere: zero block: zero, sphere: slightly less than v0
