A) What equation is used to find the vertex form of a parabola with the vertex (h, k)?

VikaD [51]

Y=ax2+bx+c . In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .

What is the net force on a Mercedes convertible traveling along a straight road at a steady speed of 100 km/h?

luda_lava [24]

Answer:

5) 0 N

Step-by-step explanation:

According to Newton's second law of motion: "The acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the object's mass" .

Because the vehicle travels at a constant speed, its acceleration at zero, so

$A=F_{net}/m$ ,

$F_{net}=A*m; A=0\\F_{net}=0$
