Final answer:
The mass of the object is 6.8 kg.
Step-by-step explanation:
In order to find the mass of an object, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). Rearranging the formula, we have mass (m) equals force (F) divided by acceleration (a). Plugging in the given values, we have:
m = F / a = 17 N / 2.5 m/s² =
6.8 kg.
