Question
The velocity of a freely falling body, starting at rest and after one second is___.
Answer: Option A
:
A
Any body in free fall is under acceleration due to gravity (g) and thus accelerates at 9.8ms−2. When a body starts from rest, after one second it will gain an acceleration of9.8ms−2 and thus will be at a velocity of9.8ms−1 in the downward direction. When rounded off to the nearest integer, the answer becomes 10.
