We often think about two-dimensional motion in terms of a projectile, like someone throwing a ball up in the air. Consider, instead, the surface of an air-hockey table, where the puck travels horizontally from one end of the table to the other. Imagine you’re standing at one end of the table and answer the following questions in your initial post to the discussion.

1. Describe the shape of the puck’s path, starting from the end of the table where you’re standing, as it undergoes the following types of motion:
a. acceleration in the x-direction
b. acceleration in the y-direction
c. constant velocity in the x-direction with acceleration in the negative y-direction

2. What must be true of x-velocity and y-velocity for the puck to travel at a 45-degree angle?

3. How can you make the angle steeper or shallower?

4. Can the puck follow a straight path if it’s accelerating in one or both directions? Choose your own orientation for the coordinate system.

Consider the projectile motion of two balls. Ball A is launched horizontally (no vertical component of velocity) with an initial speed of 100 m/s from an initial position 1 m above the ground. Ball B is launched straight upward (no horizontal component of velocity) with an initial speed of 1 m/s from an initial position 0.5 m above the ground. The two balls are launched at the same time. Assume that air resistance doesn’t matter in this problem and assume...

This question is about throwing a ball vertically upwards and catching the ball. Compare the part of the graph of mechanical energy vs. time before the ball is in free-fall to the part while the ball is in free fall. Carefully explain, using the concept of work done on the system, why the ball’s mechanical energy changed as it did.

Often we would like to make the user think we like him/her so we use a friendly prompt to get them to decide if they want to continue a loop. One can make a sentinel using an integer value outside of the expected input range but a more delightful way is to ask politely if: System.out.println("Do you want to play again?); In order to do this we will need a scanner and a do-while loop. For the scanner sometimes the...

Suppose a 10 kg ball makes a one dimensional collision with a 5 kg ball. Think about what could happen to the velocity of the 5 kg ball as a result of the collision. Could it remain unchanged? Could it increase? Could it decrease? Is it possible for both balls to end up traveling in the same direction after the collision? For each result you think could happen, please briefly explain why and offer an example of starting conditions that...

We like to think of growth of output in terms of its measures as being good and hence as desirable. That the composition of output changes over time is a given and is mostly for the better as it means greater efficiencies as well as new industries and products replacing older industries and products in the process known as creative destruction. But is all this necessarily good? It creates instability, uncertainty and in some cases new unique problems as unintended...
