In this lab you will launch an air-powered rocket. The rocket will be launched and land at the same height. You will launch the rocket twice. The first time you will launch it straight up. You will then predict the range of the rocket at a pre-assigned angle. You will measure the actual range.
You are not to launch the rocket without the teacher’s permission. If you launch without permission, you will receive a zero for the lab. If the individual responsible cannot be determined, then the whole group will receive the zero.
|STEP 1 || |
Follow the launch sheet's instructions and launch the rocket straight up. Using 2 stopwatches, measure the time the rocket is in the air. When you are completely ready to launch, stand behind the "line" to the right. Record your data on the math sheet.
|STEP 2 || |
Using this data, calculate the initial velocity of the rocket. Show all your steps on the math sheet.
|STEP 3 || |
Record your assigned angle on the math sheet.
|STEP 4 || |
Setup your rocket to launch according to the second sheet of launch instructions.
|STEP 5 || |
When you are completely ready to launch, stand behind the "line" to the right.
|STEP 6 || |
Work backwards from the measured range and calculate the needed time in the air measured in step 1 to give this range's result. Show your work on the math sheet.
|STEP 7 || |
Calculate the percent error in the measured time in step one. Show your work and answer on the math sheet.
|STEP 8 || |
You may work together on the math calculations but everyone is to turn in their own paper. You may work with 1 partner on the bonus formula derivation.
