Question

After an avalanche, a huge block of stone slid down a mountain and landed in the middle of a road. People in the nearby town had a very difficult time moving it out of the road. The block of stone is difficult to move because A. it has a high amount of momentum. B. has balanced forces acting on it. C. it has a high amount of inertia. D. has unbalanced forces acting on it.

Answer 1

Answer:

Option (C)

Explanation:

From Newton's law of inertia, an object at rest tends to be at rest until there is an external force applied to it.

In the given question, the rock block that fell on the road due to the avalanche contains high mass and high inertia. Due to which the block was not able to move aside. The amount of energy required to push the block aside should be more than the mass of the block. So the block has high inertia value and it will need more force than its inertia value in order to move the block of rock towards the side of the road.

Thus, the correct answer is option (C).
