Answer:

e) about 10 m/s

Step-by-step explanation:

Acceleration due to gravity is nominally* 9.8 m/s². That means the change in velocity each second is ...

(9.8 m/s²)(1 s) = 9.8 m/s ≈ 10 m/s

_____

* This is the value expected to be used in the solution of many math and physics problems. The standard value of 'g' on Earth is defined as 9.80665 m/s². It varies from place to place and with altitude. At any given place, it may also vary with time as a result of changes in mass distribution within the Earth.
