In order to find the velocity of the steel bunch twain different equations are needed.In order to find the velocity of the steel b whole heightend from the skyrocket gun on an inclined plane, the first equation must be manipulated and substituted into the second equation. Then use the average velocity to determine the surmount of a projectile being released at a different move. Physics Principles * Converting from centimeters to meters * Trigonometric functions * Quadratic rulex=-bb2-4ac2a * Know how to get the derived formu laMaterials Needed * Projectile gun * Projectile * Incline typography * carbon composition paper * 4 sheets of regular printing paper * Tape greenback * Calculator * Pen * Notebook paper Pre-Lab exercise Using the two formulas solve forv0. equivalence 1 x= v0xt(vox=v0cos? ) x=v0cos?

Tape 4 sheets of carbon paper together portraiture style, curiosity to end.Tape 4 sheets of printing paper using the same portrait style. Then tape 4 sheets of regular printing paper ass the carbon paper. Make authoritative to adjust the bottom edge of the attach sheets so that the bottom touches the ground. 2. Next, assemble the projectile gun with the incline plane. The angle of the incline plane was placed at 35 degrees and make sure the wing is secure so that it will not slip. 3. Test fire the projectile gun and record the distance in centimeters using the tape measure.This distance is used to determine how far the gun shoots the steel b both and will be used in the actual experiment. 4. Aim the projectile gun at the carbon paper, make sure you measure the distance from the steel ball to the ground. Fire the projectile gun at the paper and save up down the number 1 next to the layer where the ball hit. 5. After the first shot you can move the projectile gun backwards or forwards, depending on your decision. Fire the projectile gun and write down the number 2 for the second point.Repeat this step 8 more times and record the results on a table. 6. After all ten trials have been completed take down the printing paper sheet and measure how far between from where the bottom was to separately point of contact made with the projectile gun. 7. Use the equation v0=12gx2cos2? xtan? -y-y0 on each trial to find the velocity. Then find the average velocity for all ten trials.
