Consider a ball rolling along a level surface with negligible friction. Which would depict the force-versus time graph required to keep the ball rolling at constant speed? Use H for 'none of the above'.

Consider a ball rolling in the +x direction along a level surface with negligible friction. Which would depict the force-versus time graph required to slow the ball down at a constant rate? Use H for 'none of the above'.

Consider a ball rolling in the -x direction along a level surface with negligible friction. Which would depict the force-versus time graph required to cause it to move at a steadily increasing speed in teh -X direction? Use H for 'none of the above'.

Consider a ball rolling in the -x direction along a level surface with negligible friction. Which would depict the velocity versus time graph if a constant force of F was exerted in the +x direction? Use H for 'none of the above'.
