The after-collision velocity of the car is used in conjunction with its mass to determine its momentum after the collision. Using calculus and the concept of the derivative can accpmplish the same thing. Avoid merely treating these collision problems as mere mathematical exercises.

We Would Like to Suggest Using the Excel Spreadsheet with step size 0. Use the AM - GM Inequality to determine what shape boxes could be created by this method from the 25 x 25 square sheet to hold a volume of cu.

If a small square of the same size is cut from each corner and each side folded up along the cuts to form a lidless box, what is the maximum volume of the box?

In a lake, there is a patch of lily pads. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake? Afterward, the researchers surveyed the students on whether or not they held religious beliefs.

Use the Arithmetic Mean - Geometric Mean Inequality to find the maximum volume of a box made from a 25 by 25 square sheet of cardboard by removing a small square from each corner and folding up the sides to a lidless box.

The following equation results: Another interesting puzzle, which you may or may not consider tricky: If you answered 10 cents you are inclined to believe in religion.

Mathematical representations are just one of the many representations of physics concepts. The following Algebra Expressor graph supports this finding.

However, physics is about concepts and the variety of means in which they are represented. The results showed that the intuitive thinkers were much more likely to believe in religion.

This same argument would be true for boxes of volume and Because, according to research reported in the journal Sciencethe 10 cent answer indicates that you are an intuitive thinker, and the 5 cent answer indicates that you solve problems analytically, rather than following the ball box problem algebra instincts.

Let V equal the volume of the box. These Interactives can be found in the Physics Interactive section of our website and provide an interactive experience in analyzing the momentum of individual objects and systems of objects in collisions.

There is no x value that will satisfy these equations. If you answered 5 cents you are inclined to disbelieve. You have to interact with it! This gives us the following: Their study of Canadian undergraduate students showed that people who tend to solve problems more analytically also tended to be religious disbelievers.

The next section of this lesson involves examples of problems that provide a real test of your conceptual understanding of momentum conservation in collisions. Take the time to understand the concept of momentum conservation that provides the basis of their solution.

There are additional practice problems with accompanying solutions later in this lesson that are worth the practice. Since momentum is conserved, the total momentum after the collision is equal to the total momentum before the collision.

Expanded Investigations Modification to the Problem Statement: Before proceeding with the practice problemsbe sure to try a few of the more conceptual questions that follow. Every day, the patch doubles in size.Consider the following problem: A kg medicine ball is thrown at a velocity of 20 km/hr to a kg person who is at rest on ice.

The person catches the ball and subsequently slides with the ball across the ice. Determine the velocity of the person and the ball after the collision.

Using algebra skills, it can be shown that v = m/s. Feb 15, · A ball is thrown upward with initial velocity _____ and its height is modeled by the function f(x)=_____ find the time it takes to reach the maximum height and the maximum height. Let V equal the volume of the box. Then V = x (25 - 2x) (25 - 2x).

This equation can be rewritten as V = 1/4 (25 - 2x) (25 - 2x) (4x) which must be.

Box A contains balls numbered 1 through 9. Box B contains balls numbered 1 through 5. A box is chosen at random,and a ball is picked up from the box. If the ball has odd number,then the next ball is picked up from the same box. Else If the ball has even number,then the next ball is picked up from the other box.

Thus two balls are selected. The "Ball Box" problem The Acme Tennis Ball Company is designing a new box to ship its products.

The marketing department wants a triangular box that can hold 4 balls, as in the illustration below. The solution to Problem 1 Below (after the reminder) is the solution to the Problem 1 of the lesson Some logic problems (the topic Miscellaneous word problems of the section Word problems in this site).

Problem 1 formulation (reminder)Three boxes contain one ball each: white, black and green.
