The situation that shows a non-contact force changing the speed of an object is:
**A nail rolls off the edge of a roof and falls to the ground.**
In this scenario, the force of gravity acts on the nail after it rolls off the roof, causing it to accelerate downwards without any physical contact. The other options involve contact forces, such as hitting, raking, or pedaling, which all require direct interaction with the object to change its speed.
