To find the gravitational force of attraction between the planet and the mass, we can use Newton's second law of motion, which states that the force (F) is equal to the mass (m) multiplied by the acceleration (a):
\[ F = m \cdot a \]
Here, the mass (m) is 17 kilograms, and the acceleration (a) is 8.8 m/s².
Now we can calculate the force:
\[ F = 17 , \text{kg} \cdot 8.8 , \text{m/s}^2 = 149.6 , \text{N} \]
Rounding this to two decimal places, we find that:
\[ F \approx 150 , \text{N} \]
Thus, the gravitational force of attraction between the planet and the 17-kilogram mass is approximately 150 N.
The correct answer is b) 150 N.
