    average speed of the arrow?
    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



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

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

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