Final answer:
The force on an object with a mass of 20 kg and an acceleration of 8 m/s² is 160 N.
Step-by-step explanation:
The force (F) on an object is equal to its mass (m) multiplied by its acceleration (a). Therefore, to calculate the force, we can use the formula F = ma.
Given that the mass (m) is 20 kg and the acceleration (a) is 8 m/s², we can substitute these values into the formula:
F = (20 kg)(8 m/s²) = 160 N.
Therefore, the force on the object is 160 Newtons (N).
