Michelle and George are studying the forces and motion of a 0.8-kg low friction cart on a horizontal table. They use a spring scale to exert different amounts of horizontal pulling force on the cart, and they measure the acceleration of the cart for each pulling force. The measurements of each set of pulling force and acceleration are displayed in the table to the right. If friction is much weaker than the pulling force, which of the following is the best fit for the missing pulling force in the table? *0 pointsA. 1.99 NB. 2.18 NC. 2.72 ND. 3.38 N
