Need help with question 3 to 10. Thank youu!!

PROCEDURE 1. Draw a circle starting with the 2"d or 3" spark hole. Label this data point X.. Now draw a circle on every 6" spark hole for a total of 6 data points. 2. Make a graph of x vs. t with EXCEL for the 6 data points. X (cm) t ( s ) * [cm) + ( second ) X. to X1 XO = O to = 0 X2 to X 1 = 13.1 $1 = 0.1 X3 t3 XA X2 = 35.98 b 2 = 0.2 Xs ts X3 = 68.74 tz= 0.3 X4 = 111.28 +4 = 0.4 3. Use EXCEL to obtain the equation of the best curve-fit for x vs. t graph. 4 . Calculate V. at to, V2 at t2, and V4 at t4 by drawing tangent lines to the curve x(t). 5. Use the equation x = x(t) obtained in (3) to calculate V., V2, and V4. 6. Calculate the acceleration of the 'bob' from the equation x - x(t). 7. Prove algebraically that the graph of Vave vs t is linear and show how the slope is related to the acceleration of gravity 'g'. 8. Make a graph of Vave vs t using EXCEL and obtain the equation of the best curve fit. Using the above data table, the data points for the graphrof Vave vs t correspond to the following: Vave t Vol = (X1 - X.)/(t1 - to) (ti - to) Voz = (X2 - X.)/(t2 - to) (t2 - to) Vo3 = (X3 - X.)/(t1 - to) (ty - to) Vo4 = (X4 - X.)/(ti - to) (t4 - to) Vos = (Xs - X.)/(t, - to) (ts - to) Vos = (X6 - X.)/(ti - to) (to - to) 9. Calculate the acceleration of the 'bob' from the graph of Vave vs t. 10. Calculate the initial velocity V. of the 'bob' from the graph of Vave Vs t. 11. Calculate instantaneous velocity of the 'bob' V4 at ta graphically
