Question
The velocity of a freely falling body, starting at rest and after one second is___.
Options:
A .  10 ms−1
B .  15 ms−1
C .  100 ms−1
D .  98 ms−1
Answer: Option A
:
A
Any body in free fall is under acceleration due to gravity (g) and thus accelerates at 9.8ms2. When a body starts from rest, after one second it will gain an acceleration of9.8ms2 and thus will be at a velocity of9.8ms1 in the downward direction. When rounded off to the nearest integer, the answer becomes 10.
