1 Overview Ballistics is the science of projectile motion and impact, phenomena well described by Newtonian mechanics. The number of applications of this type of analysis is staggering, ranging from such mundane issues as automobile accident simulations and optimal golfing to the critical studies of missile defense and space exploration. Somewhat less dramatically, in this project we will use Newtonian mechanics to describe the flight of a sponge dart, light enough so that air resistance will play a critical role. 2 Experimental Data The data for this project was collected by firing sponge darts from a toy gun ($3.99, WalMart). The table below shows a set of measurements for distance traveled (by the projectile) versus angle of inclination of the gun, taking angles of inclination 5, 10, 15, . 85 degrees. The darts were fired from a height of . 18 meters. Angle of 5 Inclination Distance 10 15 20 25 30 35 40 45 4.37 5.23 6.95 7.84 8.17 8.69 8.81 8.99 8.95 Traveled Angle of Inclination…

I PRELIMINARY QUESTIONS 1. One of the timing devices Galileo used was his pulse. Drop a rubber ball from a height of about 2 m and try to determine how many pulse beats elapsed before it hits the ground. What was the timing problem that Galileo encountered? 2. Now measure the time it takes for the rubber ball to fall 2 m, using a watch or clock with a second hand or seconds display. Did the results improve substantially? 3. Roll the hard ball down an incline that makes an angle of about 10° with the horizontal. First use your pulse and then your watch or clock to measure the time of descent. 4. Do you think that during Galileo's day it was possible to get useful data for any of these experiments? Why?

Suggest some likely sources of error that could be responsible for the difference between your measured and predicted values for the horizontal distance traveled by the projectile at the different angles used in this experiment. “Human error” is not acceptable without saying specifically what error the human could have made.  “Calculation error” is also not acceptable—if you are worried about whether the calculation is correct, consult with your classmates and/or someone you trust to do the calculation correctly. PROCEDURE   Part I   Place a marble launcher on the table, oriented so it points straight upward (θ = 90°).  Pull the launch mechanism back to the first (nearest) launch position and place a marble into the launcher.  Practice quickly releasing the launch mechanism and get a sense for the maximum height the marble will reach after it is launched. Hold a meter stick beside the marble launcher so that the zero end is beside the marble. Launch the marble and record the maximum…

A small steel ball bearing with a mass of 14 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.35 m. Calculate the horizontal distance the ball will travel if the same spring is aimed 26degrees from the horizontal. Use kinematic equations Fast pls i will rate
