Answer 1

The situation that describes a non-contact force changing the speed of an object is "a gust of wind blowing a leaf away."

In this scenario, the leaf is being accelerated by the force of the wind, which is a non-contact force. The other options involve contact forces (like friction or applied force from pedaling).
