Projectile This problem requires the student to determine the distance a projectile will travel when thrown off a cliff with a given initial velocity. It provides explicit help in differentiating the vertical and horizontal components of motion, then determining the correct application of formulas. The problem is accompanied by a sequence of questions designed to encourage critical thinking and conceptual analysis before dealing with the mathematics.

To find the domain and range, make a t-chart: Notice that when we have trig arguments in both equations, we can sometimes use a Pythagorean Trig Identity to eliminate the parameter and we end up with a Conic: Parametric Equations Eliminate the parameter and describe the resulting equation: Eliminate the parameter and describe the resulting equation: Sometimes you may be asked to find a set of parametric equations from a rectangular cartesian formula.

This seems to be a bit tricky, since technically there are an infinite number of these parametric equations for a single rectangular equation. And remember, you can convert what you get back to rectangular to make sure you did it right!

Work these the other way from parametric to rectangular to see how they work! And remember that this is just one way to write the set of parametric equations; there are many! Here are some examples: Now, the second point: Easier way using vectors: The parametric equations are.

The parametric equations are: Try it; it works! Applications of Parametric Equations Parametric Equations are very useful applications, including Projectile Motion, where objects are traveling on a certain path at a certain time.

It appears that each of the set of parametric equations form a line, but we need to make sure the two lines cross, or have an intersection, to see if the paths of the hiker and the bear intersect.

So that answer to a above is yes, the pathways of the hiker and bear intersect. We can see where the two lines intersect by solving the system of equations: At noon, Julia starts out from Austin and starts driving towards Dallas; she drives at a rate of 50 mph.

Marie starts out in Dallas and starts driving towards Austin; she leaves two hours later Julia leave at 2pmand drives at a rate of 60 mph. The cities are roughly miles apart.Unit Four: Projectile Problem 2 Problem 2: Robin stands near the edge of a cliff in the desert.

She shoots an arrow into the air from a height of feet above the ground below with a vertical velocity of 40 feet per second a height and a horizontal velocity of 30 feet per second (sending it over the cliff). To illustrate the usefulness of the above equations in making predictions about the motion of a projectile, consider the solution to the following problem.

Example A pool ball leaves a meter high table with an initial horizontal velocity of m/s. Blast a car out of a cannon, and challenge yourself to hit a target!

Learn about projectile motion by firing various objects. Set parameters such as angle, initial speed, and mass. Explore vector representations, and add air resistance to investigate the factors that influence drag. Physics (from the Ancient Greek φύσις physis meaning "nature") is the fundamental branch of leslutinsduphoenix.com primary objects of study are matter and energy.

Physics is, in one sense, the oldest and most basic academic pursuit; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world.

Solving projectile problems with quadratic equations Example: A projectile is launched from a tower into the air with initial velocity of 48 feet per second. Its height, h, in feet, above the ground is modeled by the function.
