An object with a mass of 6.0 kg accelerates 4.0 m/s 2 when an unknown force is applied to it. The amount of force i
s 24.0 N.
This can be found using Newton's Second Law of Motion, which states that force is equal to mass times acceleration (F = ma). Given that the mass of the object is 6.0 kg and the acceleration is 4.0 m/s^2, we can plug these values into the formula to find the force:
F = (6.0 kg)(4.0 m/s^2) = 24.0 N
Therefore, the amount of force applied to the object is 24.0 N.
