Answer:

a. more friction decreases speed

Explanation:

Friction drag force causes objects to slow down as they move through a fluid, such as air or water. ... As an object's speed increases, the drag force from the fluid increases exponentially. • For example, when you drive at high speeds, the frictional force of air on the car increases, and fuel economy decreases.
