Answer:
0.25kg
Explanation:
Newton's second law states that Force=Mass x Acceleration.
Since we are given two of the three values, we can plug them into this equation to solve for the third: Mass.
Force = 4N
Acceleration = 16m/s/s
4 = Mass x 16
Divide both sides by 16 so Mass is by itself on one side:
4/16 = Mass x 16/16
0.25 = Mass
The mass of the object is 0.25 kg (SI Units).
