Final answer:
The object's acceleration is 2.5 m/s².
Step-by-step explanation:
The object's acceleration can be determined using Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration. In this case, the net force is the frictional force due to air resistance, which is given as 1.5 N. The mass of the object is 0.60 kg.
Therefore, we can use the formula:
Force = mass x acceleration
Rearranging the formula to solve for acceleration:
Acceleration = Force / mass
Plugging in the given values:
Acceleration = 1.5 N / 0.60 kg = 2.5 m/s²
