Answer:
0.11 kg
Explanation:
Ft = MV
Ft = momentum 5.22kg m/s
M = mass
V = velocity 48.3m/s
Therefore
5.22 = M x 48.3
Divide both sides by 48.3
5.22/48.3 = M x 48.3/48.3
0.11 = M
M = 0.11kg
The kinetic energy is
![\frac 1 2 m v^2](https://tex.z-dn.net/?f=%5Cfrac%201%202%20m%20v%5E2)
and the height of the building doesn't matter at all.
![E = \frac 1 2 m v^2 = \frac 1 2 (2)(5)^2 = 25](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%201%202%20m%20v%5E2%20%3D%20%5Cfrac%201%202%20%282%29%285%29%5E2%20%3D%2025)

Regions in the milky way where density waves have caused gas clouds to crash into each other are called clumps.Clumps are molecular clouds (interstellar clouds) with higher density,where lots of dust and gs cores resides. These clouds are the beginning of stars.
