A. Calculating an Estimate of xAB

• Estimate the average acceleration between A and B Hint

• Estimate the speed at B

• Estimate xAB Hint
B. Calculating an Estimate of xBC
• If air resistance is (temporarily) ignored what is the net force on the rocket as it moves from B to C? Hint
• What is the acceleration of the rocket as it moves from B to C?
• Use the estimate of vB obtained earlier to calculate a value of xBC. Hint
• Add xAB and xBC to obtain a value for the height reached by the rocket.
• Use your measurements of D, X1, X2 to determine a value for H.
Estimate h. How does your value for H + h compare with your value for xAB + xBC ?
Why do you think they are different?
