Question

1. sandra pushed a wooden block and it slid across the floor. the wooden block gradually slowed down and stopped after moving 10 meters. why did the block stop moving? a the floor exerted a force that is opposite to the direction of the blocks motion. b the block ran out of force. c the floor absorbs force from the block. d all objects stop moving because their natural state is to be still.

Explanation:

This is due to friction. Friction is a force that opposes relative motion between two surfaces in contact. Here, the floor - block contact creates frictional force opposing the block's motion, causing it to stop.

Answer:

A. The floor exerted a force that is opposite to the direction of the block's motion.
