A hand exerts a constant horizontal force on a block that is free to slide on a frictionless surface. The block starts from rest at point A, and by the time it has traveled a distance d to point B it is traveling with speed v sub-B. When the block has traveled another distance d to point C, will its speed be greater than, less than, or equal to 2v sub-B? Explain your reasoning.​
