Physics

To analyze the problem and determine which statement is incorrect, let's carefully review the concepts involved:

Option A: Impulse due to the gravitational force:

The gravitational force acts vertically downward with magnitude . The object starts from rest and slides down the frictionless incline. The total time taken to reach the bottom is . Impulse is defined as the force applied over a time interval, which is equal to the change in momentum. The gravitational force causes a vertical change in momentum, and the impulse from the gravitational force is given by:

This statement is correct.

Option B: Change in momentum:

The object moves down the incline, and the component of gravitational force that accelerates the object along the incline is
