Is the ball always the same speed? - Speed ​​changes in volleyball flight

Since the volleyball is briefly at rest in the hands of the players, but moves in between, it also experiences changes in speed.

Work order

The vector of the change in speed when flying the ball:

If you consider the change in speed only between the start and end point of the movement, the following applies to it:

Δv(t0,tend)=v(tend)v(t0)=0kmH1

For the time of t0 until ½tend one obtains a speed change of:

Δv(t0,12tend)=v(12tend)v(t0)0kmH1
Note
So it makes a difference for the speed change if you look at different time intervals.
