Explain the differences between the average speed and the average velocity.
Could I have help with this average speed and velocity problem. I already know the answers"average velocity = 2.7 m/s due east, average speed = 8.0 m/s" but I need a detailed explanantion on how and why because I am not understanding and getting the same answers
Determine the average velocity for an object that moves from x = 2 m to x = 6 m in 14 seconds.
