Two identical blocks, block A and block B, are placed on different horzontal surfaces. Block A is initially at rest on a smooth surface, while block B is initially at est on a rough surface. A constant horizontal force of magnitude F, is exerted on each block After the force has been applied for a time Ar. the speeds of blocks A und 8 are eA and v. respectively. Which of the following claims indicates the correct relation between a and vy and provides the best justification for the relation? A < vp The forces between the atoms in a block and the atoms in a surface oppose the motion of the block and are greater, on average, for blockA A. B A < Ug The forces between the utoms in a block and the atoms in a surface oppose the motion of the block and are greater, on average, for block B CA> tg. The forces between the atoms in a block and the atoms in a surface oppose the motion of the block and are greater, on average, for block A D PA> P The forces between the atoms in a block and the atoms in a surface oppose the motion of the block and are greater on average, for blockB
