1. From equation 4, derive the relationship between h andsin^2 (). Let k = the slope of the graph of h vs. sin^2 (). What is the equation for the theoretical slope of the graph? (In other words, what is k in terms of,v_i et al., in this lab?) 3. Using the slope of the trend line, what is the value of the initial speed? 4. When comparing the initial speed derived from the slope and the initial speed derived from the slope, which is more appropriate: % Difference or % Error? Explain. 5. Whichever was chosen in the previous question, calculate the value. answer these analysis questions, you must do question 1 correctly for them all to be correct
