V = u + at
0 = u -9.8 x 5.5
u = 9.8 x 5.5 = 53.9 m/s
        
             
        
        
        
Answer:
An investigation is made to determine the performance of simple thin airfoils in the slightly supersonic flow region with the aid of the nonlinear transonic theory first developed by von Kármán[1]. Expressions for the pressure coefficient across an oblique shock and a Prandtl-Meyer expansion are developed in terms of a transonic similarity parameter. Aerodynamic coefficients are calculated in similarity form for the flat plate and asymmetric wedge airfoils, and curves are plotted. Sample curves for a flat plate and a specific asymmetric wedge are plotted on the usual coordinate grid of Cl, Cd,andCmc/4versus angle of attack and Cl versus Mach Number to illustrate the apparent features of nonlinear flow.
Explanation:
 
        
             
        
        
        
So you can use the equation force = mass x acceleration to do 2 x 5 to get 10 N
        
             
        
        
        
Answer:
The amount of time for the whole journey is 8 hours.
Explanation:
A truck covered 2/7 of a journey at an average speed of 40  mph. Representing 1 the total of the trip traveled, then the rest of the distance traveled is calculated as: 
So if the truck covered the remaining 200 miles at  , this means that
, this means that  of the trip represents the 200 miles. So, to calculate the total distance traveled by the truck, you apply the following rule of three: if
 of the trip represents the 200 miles. So, to calculate the total distance traveled by the truck, you apply the following rule of three: if  of the route represents 200 miles, the integer 1 (which represents the total of the route), how many miles are they?
 of the route represents 200 miles, the integer 1 (which represents the total of the route), how many miles are they?

miles= 280 
So the total distance traveled is 280 miles. Since speed is the relationship between the space traveled by an object and the time used for it ( ), then if the average of the entire trip was 35 mph and the distance traveled 280 miles, the time is calculated as:
), then if the average of the entire trip was 35 mph and the distance traveled 280 miles, the time is calculated as:

time= 8 h
