9.8 m/s

10 m/s

none of these

​

Answer 1

Answer:

An acceleration value indicates the amount of velocity change in a given interval of time. ... For example, if a projectile is moving upwards with a velocity of 39.2 m/s at 0 seconds, then its velocity will be 29.4 m/s after 1 second, 19.6 m/s after 2 seconds, 9.8 m/s after 3 seconds, and 0 m/s after 4 seconds.
