Question 5 if you launch a projectile from the origin, the trajectory of the projectile is a downward-pointing parabola. a. write the function y(x) for this parabola using the equations of motion in terms of vix and viy without using sine and cosine and, of course, g. this is also an equations of motion; one that does not explicitly contain the time and in two dimensions. this is the standard form for a parabola. y=-m(x - h)^2 + k b. find the vertex of the parabola (h, k). what is scale factor m? c. re-write the function y(x) in this form. d. repeat question 4 using the standard form of the parabola.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
