Can you explain how I would solve the data table and the equations I would need?

B. Determination of /x (accelerated motion) Table 33: Wood on Aluminum my = 130.15 g mn E Edge/Flat: 45 g Weighted: 90 g my = 130.00 g a HK mb (flat) 0.455 % diff mb (edge) 0.598 mb + my 0.436 Table 4: Felt on Aluminum mb 130.15 g my = Edge/Flat: 55 g Weighted: 110 g my = 130.00 g a mb (flat) 0.412 % diff mb (edge) 0.507 mb + my 0.408
