for speed divide the distance by the time
for velocity divide the DISPLACEMENT by the time
displacement is a vector with x y and perhaps z components. All the way around a track is a Distance of 2 pi r BUT a displacement of ZERO
The winner of the Kentucky Derby runs the 1.25-mile race in 2 minutes, 2.0 s.
What's the horse's average speed in m/s?
A Message from Your Instructor:
Velocity refers to the displacement from the initial point to the final point. For the first part, determine where the car ends up in relation to the starting point. Speed refers to the total distance traveled, regardless of direction. For the second part just find the total distance traveled by the car.
