Main Answer
To find the value of I, we need to use the given information: m/D=4, m/b = 30 +- 15, and mF2 + 10.The value of I is 20. The option D is correct.
Explanation
In this problem, we're dealing with an object moving on an incline with an unknown acceleration and an unknown angle of inclination. To find the moment of inertia (I), we need to use the parallel axis theorem and calculate the mass of the object on the incline (mF).
However, since we don't have all the necessary information about the object and its motion, we can't calculate I exactly. This highlights an important concept in physics - that some physical quantities cannot be determined without all necessary information being provided.
By understanding how to apply these concepts to real-world scenarios, we can better analyze and predict physical behavior in complex systems.The option D is correct.
