# need help with a part of lab

lab is called projectile launcher lab

need help with the following

• Draw a diagram of the setup showing all appropriate measurements and labels using proper format
• Indicate the calculated and measured ranges on the figure
• Include launch velocity and final velocity of the projectile on the diagram
• Include the written description of the steps to your solution here.
• Calculate the percentage error for your experiment
• What may be the cause of this error?
• What is the optimal launch angle to obtain the longest range?
• Explain one practical application of projectiles (no wartime applications please)

data collected is

The students measured the time it took their plug to fly up and then back down. The average time for 4 of the plugs was 1.72 seconds. You can use that number in your calculations. As per the instructions, you should be able to now do the calculations to come up with the range of any given angle. You can choose the angle you want to launch the plug at… 30°-80° increasing by 5’s. the height of the launcher for the angle of 40° is 1.02 m.)

(you can choose any angle for this)

Purpose:

To determine the target location of a projectile launched from a specific height and angle.
