The arrow's initial upward speed is 50m/s, and 5 seconds later its zero. What's the average speed of the arrow during this time?

what is the average speed of the arrow on the way back down-that is, for a beginning speed of zero and final speed of 50m/s?

I just want to know how to calculate this equation
thanks for helping :)

The average velocity is the distance traveled by the arrow divided by time. So, how high does the arrow travel in 5 seconds? You can use


v_f^2- v_i^2 = -2gd


to calculate d, given that v_i = 50 m/s and v_f = 0.

On the way down the arrow will have the same average speed, although in the downward direction.

Average speed and average velocity [ 2 Answers ]

Every morning you jog around 250 meter track four times in 30 minutes. What is your average speed and average velocity?
