A small toy airplane is flying in the xy-plane parallel to the ground. In the time interval t=0 to t=10.0 s, its velocity as a function of time is given by

Incomplete.

To answer your question, I would need the given function that describes the velocity of the toy airplane as a function of time in the interval t=0 to t=10.0s. Could you provide the function?

To determine the velocity function of the toy airplane, we need more information. The problem statement you provided is incomplete. Please provide the velocity function or any additional information you have.
