which is an example of negative acceleration?\n○ a snowboarder who increases speed when traveling downhill\n○ a biker who maintains a constant speed through a race\n○ a skateboarder who reduces speed when moving up a hill\n○ a runner who fluctuates speed by increasing and decreasing speed

Answer

Brief Explanations:

Negative acceleration (also called deceleration) occurs when an object's speed decreases. A snowboarder increasing speed has positive acceleration. A biker with constant speed has zero acceleration. A skate - boarder reducing speed moving up a hill has negative acceleration. A runner fluctuating speed has variable acceleration but not specifically negative acceleration all the time.

Answer:

a skateboarder who reduces speed when moving up a hill
