Answer:The skateboarder’s acceleration is -2.33 m/s².

Explanation:The acceleration of an object is a magnitude that indicates how the speed of the object changes in a unit of time. That is, acceleration is the change in speed in a unit of time.

Acceleration is calculated as the relationship between the variation or change in the speed of a mobile and the time used for said change:

In this case:

Replacing:

and solving you get:

acceleration= -2.33 m/s²

The skateboarder’s acceleration is -2.33 m/s².
