Question

For a truck moving at constant speed...

1. the distances traveled during each time period are the same. 2. the direction traveled during each time period must be the same.

3. the truck must accelerate.
4. all of these.

Answer 1

1.) the distances travelled during each time period are the same

Step-by-step explanation:

1.) is correct. If the speed is constant, the truck is moving the same distance per every time period. For example, if the truck is moving at 50 miles/hour, the truck will always travel 50 miles per every 1 hour.

2.) is incorrect. Unlike the velocity, speed is non-directional. This means a truck can maintain a constant speed regardless of its orientation.

3.) is incorrect. Acceleration is the rate at which the velocity/speed changes. If the speed is constant, the acceleration is 0.

4.) is incorrect.
