m3=Explanation / Answer
from the slope delataa/deltaF
from newtons second law
F = m*a
a/F = (1/m)
+
for graph 2
(5a - 4a)/(5-4) = 1/0.2
a = 5 m/s^2
++++++++++++
for graph 1
(5a-0)/(2-0) = 1/m1
(5*5)/2 = 1/m1
m1 = 0.08 kg
++++++++++++++++
for graph 3
(2.5a-0)/(6-0) = 1/m3
(2.5*5)/6 = 1/m3
m3 = 0.048 kg = 0.05 kg
