This is a typical high school physics exercise. It involves a real situation of sliding of a block on an inclined plane and focuses on analyzing how the forces act on it in this scenario. It is usually guided by three basic forces: Weight, Normal and Friction.
We have the decomposition of the Weight on the X axis and the Y axis. The Normal force will act in the opposite direction to the Weight in Y and the frictional force will be opposite to the weight in X, so the greater the frictional force, the less the block will move or remain stationary, however, otherwise, the block will descend the inclined plane with greater or lesser speed depending on the frictional force. The below application shows a simulation of this scenery with the forces diagram and the main equations.
