Answer:
The force of gravity
Explanation:
Gravity was studied, by early scientists such as Copernicus and others, Galileo was the first to ensure that planets moved according to a physical equation that depended on a force that caused celestial bodies to move and interact with each other. But years later Newton based on studies conducted deciphering what Galileo assumed, he was able to find the equation of the force of gravity in any body in the universe. This equation depends on the masses of the two interacting bodies, the distance between them and a constant, which I call universal gravitation constant.

Fg = gravity force [N]
G =  universal gravitation constant = 6.67*10^(-11) [N*m^2/kg^2]
m1 = mass of the 1st body [kg]
m2 = mass of the 2nd body [kg]
r = distance between the bodies [meters]
 
        
             
        
        
        
Answer:

Explanation:
Given:
- angle of launch of projectile from horizontal,  
- range of projectile,  
<u>We have formula  for the range of projectile:</u>

putting the respective values

 is the velocity with which Tom should jump to land on the other roof.
 is the velocity with which Tom should jump to land on the other roof.
 
        
             
        
        
        
Answer:
The value is      
Explanation:
From the question we are told that 
     The velocity which the rover is suppose to land with is   
 
     The  mass of the rover and the parachute is   
 
      The  drag coefficient is   
 
       The atmospheric density of Earth  is  
      The acceleration due to gravity in Mars is  
      
Generally the Mars  atmosphere density is mathematically represented as 
           
=>        
=>        
Generally the drag force on the rover and the parachute  is mathematically represented as 
           
=>        
  
=>        
  
Gnerally this drag force is mathematically represented as 
          
Here A is the frontal area 
So   
          
=>       
=>
