Answer:
Given: 6 questions with certain values of mass and acceleration.
To find: The amount of force?
Solution:
An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
          F = m x a = 2 x 2 = 4 N
An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
           F = m x a = 5 x 8 = 40 N
An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
Now in this mass is in grams, so converting it kg, we get:
          1500/1000 kg = 1.5 kg
          F = m x a = 1.5 x 10 = 15 N
