Answer:
288N
Explanation:
Given parameters: 
Mass of Cheetah = 12kg 
Acceleration  = 24m/s² 
Unknown: 
Force needed by the cheetah to run  = ? 
Solution: 
The force needed by the Cheetah to run is the net force. 
According to Newton's law; 
     Force  = mass x acceleration
Insert the given parameters and solve; 
    Force  = 12 x 24  = 288N

Answer:
Net forces which pushes the window is 30342.78 N.
Explanation:
Given:
Dimension of the office window.
Length of the window =  m
 m
Width of the window =  m
 m
Area of the window = 
Difference in air pressure = Inside pressure - Outside pressure 
                                            =  atm =
 atm =  atm
 atm
Conversion of the pressure in its SI unit.
⇒   atm =
 atm =  Pa
 Pa
⇒  atm =
 atm =  Pa
 Pa
We have to find the net force.
We know,
 ⇒ Pressure = Force/Area
⇒ 
⇒ 
⇒ Plugging the values.
⇒  
 
⇒  Newton (N)
 Newton (N)
So,
The net forces which pushes the window is 30342.78 N.
 
        
             
        
        
        
Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A: 
 
A skateboarder flies horizontally off a cement planter. After a time of 3 seconds (Δt), he lands with a final velocity (v) of −4.5 m/s. Assuming the acceleration is -9.8 m/s² (a), we can calculate the initial velocity of the skateboarder (v₀) using the kinematic equation A.

When the object is moving in the elliptical orbit, it means that the direction of its acceleration should be towards the two foci (plural of focus) of the ellipse to keep the elliptical motion. As force according to the Newton's second law: F = ma, the net force must be in the direction of the acceleration. As far as the magnitude of net force is concerned, you can use Newton's gravitational law to find its magnitude.
