Projectile motion model writeup

1. You built a catapult . Adjust it so that it is capable of launching a large marshmallow from a distance of 3 to 5 meters, and hitting a target that is .30 m high +/- .10 m. You will have 5 trials to hit your target at each distance on Friday, and will be graded according to your accuracy. (10 points)

2. Determine the variables for the y(down) and x for your catapult.  Base your calculation on d(y) and x(y), both which were measured.  SHOW WORK. (15 points)

3. Where is the biggest frictional issue in your machine? Explain why this matters to the range of your machine. (3 pts)

How could you determine F(net) of the projectile? (3 points)How will the net force of the projectile change if we use marshmallows instead of paper wads? An orange? Why?(3 points)
Explain how you would change the design if you built another machine, and what you have learned about projectiles. Include the following terms in your discussion about projectiles.: potential energy to kinetic energy changes, frictional force, net force, acceleration of gravity, vectors, kinematic equations, independent x and y motions. (15 points)

================================

Compare the physics engine used in your cartoon to the physics engine used in your game, using the data you captured in screen shots to support one of the following:

1.  Both the cartoon and the game have great physics.
2.  Neither the cartoon or the game have great physics.
3.  One of the two is obviously superior.

This should be close to a page when done
================================

Use your paperwad data and see how close your value of C in the quadratic analysis came to -5 m/s/s
In fact, you can calculate the percentage error by using (x-5)/5, since the acceleration of gravity is 10 m/s/s.

Why does your data match or not match this idea?

Explain, using your screen shot as evidence.
