In revision to find the velocity of the marque stumblebum 2 different equivalences are needed.In order to find the velocity of the trade name ball fired from the projectile artillery on an escaped plane, the first comparability must be manipulated and substituted into the second equation. wherefore use the average velocity to peg plenty the distance of a projectile existence released at a different angle. physical science Principles * Converting from centimeters to meters * Trigonometric functions * Quadratic form ulax=-bb2-4ac2a * Know how to get the derived formulaMaterials require * Projectile munition * Projectile * bend piece * Carbon paper * 4 sheets of rhythmical effect paper * taping Mea trusted * Calculator * Pen * notebook computer paper Pre-Lab exercise Using the two formulas solve forv0. Equation 1 x= v0xt(vox=v0cos? ) x=v0cos? (t) t=xv0cos? Equation 2 y= y0+v0yt-12gt2(v0y=v0sin? ) y= y0+v0sin? xv0cos? -12gxv0cos? 2 y= y0+xsin? cos? -12gx2v02cos2? Procedure 1. Tape 4 sheets of carbon copy paper together portrayal style, end to end.Tape 4 sheets of printing paper using the same depicting style. Then tape 4 sheets of regular printing paper behind the carbon paper. Make sure to adjust the loafer edge of the taped sheets so that the lav touches the ground. 2. Next, assemble the projectile gun with the incline plane. The angle of the incline plane was rigid at 35 degrees and suffer sure the wing is secure so that it result not slip. 3. Test fire the projectile gun and re cord the distance in centimeters using the tape measure.This distance is utilize to determine how far the gun shoots the steel ball and will be utilize 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. burning the projectile gun at the paper and write eat the number 1 next to the vertex where the ball hit. 5. later the first torpedo 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. reverberate this step 8 more generation and record the results on a table. 6. After all ten trials have been realised take down the printing paper sheet and measure how far between from where the bottom was to each point of middleman 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.
