1. Complete each table in the following way: a) Use the mass listed to determine the total weight of the pulled block. Show a sample calculation for one of the masses in the space below. Fg= b) Knowing that each block was pulled along a horizontal surface at constant speed, use your knowledge of Newton's 1st Law of Inertia to complete the tables by listing the correct friction force and normal force acting on each block.

Total mass pulled (kg) 0.35 1.10 0.77 0.52 2.04 0.91 Horizontal pulling force (N) 0.9 2.8 2.0 1.3 5.2 2.3 Total weight of pulled block (N) Friction force acting on block (N) Normal force acting on block (N)
