ANGRY BIRDS LAB

Objective: To be able to calculate where a projectile will hit when launched at a certain angle from a certain height.

Prelab Questions

1. An angry bird is fired at a pig hanging in a tree. If the bird is fired at an angle of 35 degrees with a velocity 58 m/s and hits the pig which is 100 m away how high off the ground is the pig?

1. A bird is shot off the edge of a cliff toward a pig on the ground. The cliff is 37 m high and the bird is shot with a velocity of 22 m/s at 10 degrees below the horizontal. How far away is the pig from the base of the cliff if the bird ends up hitting the pig?

1. A bird is shot from the top of one building to the top of another building 4.0 m away. The bird leaves the slingshot at an angle of 15 degrees with respect to the flat floor while traveling at a speed of 5.0 m/s. Will he make it to the other roof, which is 2.5 m shorter than the building he is shot from?

LAB
For each of your targets, develop a scenario in order to prove that your angry bird can hit the target.

1. Find the initial velocity of your projectile using methods that we have used in the past. Check your methods and calculations with Mrs. Brown before continuing.

1. Determine a way to steady your projectile so that you can accurately measure the angle that it is shooting from while positioned on a platform. Record the height of you platform on the data sheet under yi.
2. Place an angry bird on your blocks at some specified height yf. Record yf on your data sheet and the distance from your launch position xi to the target on your data sheet at xf.
3. Determine the angle with which you need to shoot your projectile at in order to hit the angry bird at y1. Record that angleӨ on your data sheet.
4. Using your data, and the following values: xi, yi, yf, vi, and the launch angle Ө prove that you can in fact find xf for your launcher.

CONCLUSION QUESTIONS

An angry bird leaves the edge of a 12 m tall cliff with a velocity of 4.8 m/s at an angle of 23 degrees above the horizontal.

1. How long is he in the air for?
2. How far from the base of the cliff does he land?
3. What is his impact speed upon impact with the ground?
