4. In an experiment, a constant force was applied to different masses causing them to accelerate. The mass values in kg and their accelerations in m/s2 were recorded: Mass acceleration (kg) (m/ s? ) 2.5 1 . 985 2.5 2. 196 2 . 5 1 . 648 2.5 1 . 455 3 .5 1. 135 3.5 1 . 235 3 . 5 1. 733 4.0 1. 131 4.0 1 . 168 4.5 1. 071 4 .5 0 . 988 5 . 0 0 . 960 5 .0 0. 961 5 .5 0 . 809 5 .5 0 . 911 5 .5 0 . 579 6.0 0 . 415 6.5 0 . 604 6.5 0 . 737 6.5 0 . 640 7. 5 0 . 461 7. 5 0 . 878 7.5 0 . 816 7.5 0 . 550 9 . 5 0 . 405 9 . 5 0 . 411 9.5 0 . 399 10.0 0. 728 10.0 0.399 11 .5 0.326 12.0 0 . 302 12.5 0. 289Acceleration (m/s)2 vs Mass (kg) Acceleration (m/s) -0.15*x + 1.83 R= = 0.7 2.5 2.0 1.5 Acceleration (m/s) 1.0 0.5 0.0 6 8 10 12 Mass (kg)
