Activity 9-2: Predictions of the Outcome of Colli-sions (a) Sketch a predicted result of the interaction between two carts that bounce off each other so their speeds remain unchanged as a result of the collision. Use arrows to indicate the direction and magnitude of the velocity of each object after the collision.

Answers may vary. Sample answers: When one puck collides with a second puck at an angle, the speed of the second puck will be less than the initial speed of the first puck, and as the angle of the collision increases, the speed of the second puck will decrease.

Find the speeds of the pucks after the collision if half the kinetic energy is lost during the collision. Answer: The collision is inelastic, since energy is not conserved.

Consider the following problem: Such a motion can be considered as a collision between a person and a medicine ball. Before the collision, the ball has momentum and the person does not. The collision causes the ball to lose momentum and the person to gain momentum. After the collision, the ball and the person travel with the same velocity (v) acros...
Now consider a similar problem involving momentum conservation. Before the collision, the ball has momentum and the catcher's mitt does not. The collision causes the ball to lose momentum and the catcher's mitt to gain momentum. After the collision, the ball and the mitt move with the same velocity (v). The collision between the ball and the catche...
Now we will consider the analysis of a collision in which the two objects do not stick together. In this collision, the two objects will bounce off each other. While this is not technically an elastic collision, it is more elastic than the previous collisions in which the two objects stick together. In this collision, the truck has a considerable a...
To express an understanding of the law of momentum conservation by comparing momentum changes and total system momentum for a collision. To use the law of momentum conservation to analyze a collision problem and to determine an unknown quantity.
E1 Waiting to be fired: weight of human cannonball, upwards force from the platform they are standing on. The resultant force is zero as their motion is not changing. Being fired: weight acting downwards and upwards force from the platform which is greater than their weight, so there is a resultant force acting upwards.

A General Method for Solving a Problem That Involves a Collision 1. Draw a diagram of the situation, showing the velocity of the objects immediately before and immediately after the collision. 2. In a two-dimensional situation, set up a table showing the components of the momentum before and after the collision for each object. 3.
