No. You have the units wrong.
Example with numbers:
When you multiply (1/9) by 2, you get 2/9 .
With units:
When you multiply (m/s) by (kg), you get (kg-m/s).
To find the center of mass of an irregular shape using
String- for hanging at the center
• A small mass - hung from the string
• A stand-holding up the string
• A pencil pinpointing the center
• A straight-edge- Identify the middle

#SPJ1
H = 280 ft, the height of the flower pot.
g = 32 ft/s²
Neglect air resistance.
Note that 1 ft/s = 15/22 mi/h
The initial vertical velocity is zero.
Let v = the velocity with which the flower pot hits the ground.
Then
v² = 2gh
= 2*(32 ft/s²)*(280 ft)
= 17920 (ft/s)²
v = 133.866 ft/s
Also,
v = (133.866 ft/s)*(15/22 (mi/h)/(ft/s)) = 91.272 mi/h
Answer: 133.9 ft/s or 91.3 mi/h
