Question

which statement best describes the motion of the toy vehicle during the first 30 seconds of the investigation?

the vehicle was traveling at a constant speed.

the acceleration of the vehicle was increasing.

the vehicle was accelerating at a constant rate.

the speed of the vehicle was increasing.

Explanation:

To determine the motion of the toy vehicle, we analyze each option:

• "The vehicle was traveling at a constant speed" is incorrect if speed changes (e.g., accelerating).
• "The acceleration of the vehicle was increasing" would imply a non - constant acceleration, but without data suggesting that, this is not likely.
• "The vehicle was accelerating at a constant rate" would mean a linear increase in speed, but we don't have info to confirm constant acceleration.
• "The speed of the vehicle was increasing" is a general and often correct description for a toy vehicle's motion in the initial seconds (e.g., if it's a battery - powered or motor - driven vehicle, it speeds up from rest or low speed).

Answer:

D. The speed of the vehicle was increasing.
