Answer: the acceleration of the object is approximately 2500 m/s².
Step-by-step explanation:
To find the acceleration of the object, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
Mathematically, this can be expressed as:
F = m * a
Where:
F is the force applied to the object (140 N)
m is the mass of the object (56 g = 0.056 kg)
a is the acceleration of the object (unknown)
Rearranging the formula, we have:
a = F / m
Substituting the given values:
a = 140 N / 0.056 kg
a ≈ 2500 m/s²
Therefore, the acceleration of the object is approximately 2500 m/s².
