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 case, the force of the wind acts on the leaf from a distance, causing it to move, which is an example of a non-contact force (specifically, a gravitational or air resistance force). The other options involve contact forces where direct physical interaction occurs.
