If the ball started off stationary and the acceleration is the same for the 2 seconds, then the acceleration of the ball is:
Speed / time = acceleration
9 (m/s) / 2 (s) = 4.5 (m/s/s)
Hope this helps.
Acceleration is measured in m/s2 (metres per second squared)
it is 10 meters per second straight down
you doing homework???
It is not possible to answer this question without the starting velocity.
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
Acceleration is measured in m/s2 (metres per second squared)
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
it is 10 meters per second straight down
.5 meters per second.

It is not possible to answer this question without the starting velocity.
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
19.6 meters per second or about 44mph
20 meters per second
-2.33 metres per second squared
Half a second every metre.
If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
