page. 5. Write down each person's name and their total flight time in the data table on the next 7. Now repeat the above steps for the other two launches in each case, solving for initial Calculations: velocity (v) and maximum height (d). Be sure to use each of the two possible equations for maximum height in order to Using the kinematics equations for constant acceleration, FIRST perform the following gain familiarity with each of them. Enter this information in the data table. results to calculations for YOUR launch. Then repeat the calculations for the other two launches. Lastly, Equations: g = -9.8 m/s Data: V. = vi+ gt Maximum Total Time Time to Apex Initial Velocity Ax = vit + 1/2 gt Name Height (m) seconds (seconds) (m/s v,2 = v2+ 2gAx 3.2 1s 1.605 s 12. 65 m Megen 15. 76 m / s The apex is the peak of the rocket's flight. Calculate the time it takes the rocket to reach Petrica 3.34s 1. 675 16.37 75 13.67 m ts apex, which is equal to 1/2 the total flight time. Enter this information in the data table. 2. Make a mini-sketch of the path of the rocket launch and landing. (on the last page) Natalie 3. 16s 1.58s 15.48 m/s 12.2m Label the ground level "x ," and the highest point "X,." Next to the x's, write the corresponding symbols for initial and final velocity. What section(s) of your sketch do you think would be represented by t and 1/2 t? Label t and 1/2 t. Conclusions: 3. Taking into account the variables for which you have data, select an equation that could be 1. What was the rocket's velocity at the apex of its flight? used to determine the initial launch velocity of the rocket. Write the equation below. 2. What is the rocket's speed just before it hits the ground equivalent to? Vf = Vi+ gt 3. Rank your three launches in terms of lowest to highest initial velocity and lowest to 4. Use the equation you chose in #3 to calculate the initial velocity of your launch only. highest maximum height. . Be sure to recopy the equation and rewrite all the variables you have data for, solve data table. for the initial velocity showing all work. Fill in the initial velocity for your launch in the (Highest v.) (Lowest v) (Highest apex) (Lowest apex) 5. Now, again taking into account the variables that you now do have data for, what equations could be used to determine the maximum height achieved by the rocket? 4. What is the relationship between the initial velocity and the apex of the rocket? A x = Vit + z gt 2 or vez = vi 2+2q Ax 6. Use either of the equations you chose in #5 to calculate the maximum height of your rocket. 5. Explain how you could use this method to calculate the height of fireworks? Show ALL work and steps as you did in #4. Enter this information in the data table
