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

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
The student's velocity is 4 meters per second. Velocity is calculated by dividing the distance traveled by the time taken. In this case, 20 meters divided by 5 seconds equals 4 meters per second.
.5 meters per second.
The MKS (meter-kilogram-second) unit of velocity is meters per second (m/s). It represents the distance traveled in meters per unit of time in seconds.

20 meters per second
-2.33 metres per second squared
Half a second every metre.
