time: 0. 665 rangle: 5-ozm Virtual Lab 1 height: 2.1Im 11) Use the crosshair circle and measure the maximum vertical height at the peak of the projectile's path. Record the "Height" number from the box onto your data sheet. That is the maximum height of the projectile. 12) Calculate the percent discrepancy of the maximum height between your calculated value and the measured value, using the measured value as base. Question #1: There is another angle that can achieve the same horizontal range without changing the initial speed. What is that other angle? Verify your answer using the simulator. Question #2: If there is air resistance, will the two angles in Part II and Question #1 produce the same horizontal range? If not, at which angle will the projectile travel further? (Try both angles on the simulator with the cannonball at maximum diameter.), air resistance between them dues not affect where it lands, but it does affect the number of range. Procedure Part III - Firing a projectile horizontally from a cliff 13) Raise the cannon to a height of your choice and record that height onto your data sheet. Smfor height 14) Set the angle to be 0 and choose an initial speed (no more than 15 m/s). Record both on your data sheet. 12 mitral speed 15) Input the angle and the initial speed into the simulator and FIRE! 16) Place the crosshair at the end of the path and copy the "Range" number from the box onto your data sheet. The "Range" number is the horizontal distance from the base of the column to where the projectile has landed. time : 1. 015 renege: 12. 09 m Procedure Part IV - Target Practice heght : om 17) Lower the cannon back to ground level. 18) Place the red target somewhere from the canon and record its distance on the data sheet. Use trial and error and find TWO sets of initial speed and angle combinations that will hit the center of the target (three stars). Record both sets of data on your data sheet. 15m 350 Lab Report initialsneed 12mis time 1. 535 range : 15.03m Part III heght om 1) Using the angle and the initial speed from part III, along with the initial height of the 60 610 projectile, calculate the horizontal range of the projectile from the base of the column. inthalsneed 2) Find the percent discrepancy of the horizontal range between your calculated value and the 13 mls simulation value from 16 using the simulation value as the base. 15 m time 2. 45 Renege 15. 05 m 179 height Om
