No.  'Thrust' is what most people in aviation call the force 
that pushes the aircraft forward.  
The same people generally call the upward force on the wing "lift".
        
             
        
        
        
Answer:
A. It does not exhibit projectile motion and follows a straight path down the ramp.
 
        
                    
             
        
        
        
Newton’s Second Law concerns the generation of force based on an object’s mass and acceleration, as described by the equation F=ma. 
Hope this helps!
 
        
                    
             
        
        
        
The amplitude is from the absolute value of the 0 point on the y-axis to the highest(peak) or lowest(troph) point of the wave. In this question, 3cm is the highest and -3cm is the lowest, so the amplitude is 3cm.
