Answer:
The speed of Alessandra's motion is 2 ft/s up.
(C) is correct option.
Explanation:
Given that,
Time = 1 sec
Height = 2 feet
We need to calculate the speed of Alessandra's motion
Using formula of speed
[tex]v=\dfrac{d}{t}[/tex]
Where, v = speed
d = height
t = time
Put the value into the formula
[tex]v=\dfrac{2}{1}[/tex]
[tex]v=2\ ft/s[/tex]
The direction will be up ward.
Hence, The speed of Alessandra's motion is 2 ft/s up.
(C) is correct option.
