P = mv
This is a momentum question:
Momentum is always conserved so the momentum before and after a collision must be equal so:
The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by:
Where i is initial and f is final meaning before and after the collision
Answer:
2 clothing has changed bc the needs based on the environment and advancings culturs its supplied to support the needs of its wearer. It has also changed to impress others or simply to just fit in and not be left out.
Because gravity pulls towards the center of the earth evenly in all directions, giving earth a spherical shape.
<span>Interstitial fluid is the answer </span>
Potential energy=PE
PE=mgh
m=mass in kilograms.
g=9.8 m/s
h=height in meters
Data:
mass=500 Kg
h=110 m
PE=(500 Kg)(9.8 m/s²)(110 m)=539000 joules
