Answer:
0.8764kgm/s
Explanation:
Finding the velocity(v) before it hits the ground , where g is 9.8m/s²
v²= u² + 2gh
v² = 0 + 2× 9.8 × 2
v² = 40
v = √39.2
=6.26m/s
momentum= mass × velocity
= 0.14 × 6.26
= 0.8764kgm/s
Answer: It is possible to make a valid conclusion as long as the data does not pertain to one certain region.
Hope this helps! :)

The descriptions have been matched to the correct diseases that test our understanding of infections that affect the lower respiratory system as follows:

- Otitis Media- Most common cause is Streptococcus pneumonia and results in a sensation of fullness or pain in the ear
- Bacterial pharyngitis- Streptococcus pyogenes infection that results in a sore throat with reddened mucosa, swollen tonsils, and pus nodules
- Common cold- Caused by hundreds of viruses and results in sneezing, scratchy throat, and runny nose
- Sinusitis- Caused by a number of bacteria and results in nasal congestion, pressure above the nose or in the forehead, and headache
