Let's assume that the parabola has the following intersections with the x axis:
x1 = p
x2 = q
To find the equation of the parabola, we write the following product of binomials:
(x-p) (x-q) = 0
Where,
p, q: intersections with the x axis.
When developing the product of binomials, we obtain the equation of the parabola.
Answer:
(x-p) (x-q) = 0
The correct answer to the physics problem in pressure given above would be 1.5 N.
First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).
Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)
Consequently, I used the equation of pressure (P = Force/Area).
P = 461.58 N / .00314 m^2
P = 1.47 or 1.5 N
