Speed = distance / time
S= 40 000m / 5400s
S= 7.41m/s
        
             
        
        
        
the height of the building is H=36 m.
<h3>What is The Law of Gravity?</h3>
According to Newton's law of gravity, every particle of matter in the universe is attracted to every other particle with a force that varies directly as the product of their masses and inversely as their distance from one another.
Properties of Gravity - 
-  It is a universal attractive force. It is directly proportional to the product of the masses of the two bodies.
-  It obey inverse square law.
-  It is the weakest force known in nature.
Examples of Gravity -
- The force that holds the gases in the sun.
- The force that causes a ball you throw in the air to come down again.
- The force that causes a car to coast downhill even when you aren't stepping on the gas.
v₀=0 m/s
H₀=0 m
g=10 m/s²
t=7,2 s
H - ?

H = 0 +0 × 7.2 + 10(7.2)²/2
H = 36m

from what you have you can plug into your formulas to get time.
        
             
        
        
        
Answer:
If she is walking 30 feet every 10 seconds, that means she is walking 180 feet per minute. Multiply that by the 60 minutes in an hour, means she walks (180x60)= 10,800 feet an hour. 
She walks 3 feet a second.
She walks 180 feet a minute.
She walks 10,800 feet an hour.

Answer:

Explanation:
We know that the tangent function relates the angle of the right triangle that forms the hot air balloon rising:

Differentiating (1) with respect to time, we get:

 since x is a constant value. Replacing:
