The string exerts a constant horizontal force. Glider B is pulled also across a frictionless table by a string. The string exerts the same force on B as on glider A. Glider B has twice the mass of glider A. Both gliders start at rest. After each glider has been pulled a distance d, O the speed of glider A is smaller than the speed of glider B the speed of glider A is larger than the speed of glider B the speed of glider A is the same as the speed of glider B Previous Next Not saved Submit Q @ # N W 4 8 AR Q xx W CC E 77 R T Y A S D F G H L O Z X C V B N E TT T
