Answer:
6.14 s
Explanation:
The time the rocket takes to reach the top is only determined from its vertical motion.
The initial vertical velocity of the rocket is:

where
u = 100 m/s is the initial speed
is the angle of launch
Now we can apply the suvat equation for an object in free-fall:

where
is the vertical velocity at time t
is the acceleration of gravity
The rocket reaches the top when

So by substituting into the equation, we find the time t at which this happens:

Answer:
Two oxygen atoms
Explanation:
The majority of the oxygen in the air in our atmosphere consists of molecular oxygen (
), which consists of 2 atoms of oxygen, since free oxygen mainly form covalent bonds with other atoms of oxygen.
A small fraction of the oxygen, however, in the ozone form, which consists of 3 atoms of oxygen bond together (
).
Answer:

Answer: 10 kg</h3>
==================================================
Work Shown:
We have these variables
- p = momentum = 25 kg*m/s
- m = mass = unknown
- v = velocity = 2.5 meters per second
Solving for the mass gets us...
p = m*v
25 = m*2.5
25/2.5 = m
10 = m
m = 10
The mass of the horse is 10 kg.
