it is 10 meters per second straight down
you doing homework???
It is not possible to answer this question without the starting velocity.
The acceleration of gravity is 9.8 meters per second2 .In 3 seconds, gravity increases the falling speed by (9.8 x 3) = 29.4 meters per second.This particular ball already had a downward speed of 6 m/s when the 3 seconds began,so at the end of the 3 seconds, its velocity is(6) + (9.8 x 3) = 35.4 meters per second downward
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
-2.33 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?
.5 meters per second.

19.6 meters per second or about 44mph
The Answer Is: 4 feet per second.
20 meters per second
-2.33 metres per second squared
Half a second every metre.
The speed (magnitude of velocity) is always 9.8 meters per second (32.2 feet per second) greater than it was exactly one second earlier. If the object spent "N" seconds falling, then its speed (magnitude of velocity) is 9.8N meters per second (32.2N feet per second) greater at the bottom than it was at the top. The direction of velocity remains constant under the influence of gravity ... straight down.
