Answer:
Yes, the average speed for the entire trip from A to C is equal to
Step-by-step explanation:
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. For the special case of straight line motion in the x direction, the average velocity takes the form:
If the beginning and ending velocities for the motion are known, and the acceleration is constant, the average velocity can also be expressed as:
We Know that:
Replacing the values:
