The ball you will fire has a mass of 12.2 g. The gravitational field of the planet is 9.00 N/kg
The ball falls a vertical distance of 812.0 mm as it goes from the launcher to the ground.
Click on the zoomed in view of the launcher to fire the ball.
Use the acceleration due to gravity to find the time of flight.
Find the vertical speed of the ball right before hitting the ground.
Based on where the ball lands, determine the launch speed of the ball.

According to your data, was your hypothesis correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. list at least two real world examples that apply the findings of this experiment. (hint: an example of this type was given in the introduction to this project.)
