12. A stone is dropped from the top of a cliff. It is seen to hit the ground below
after 3.55 s. How high is the cliff?
13. A ball is dropped from rest at the top of a building that is 320 m tall. Assuming
no air resistance, what is the speed of the ball just before it strikes the ground?
14. Estimate (a) how long it took King Kong to fall straight down from the top

Review the data from the lab and determine whether your data is within standard deviations. Report, using numerical values, whether your data for each angle is within standard deviations. An acceptable margin of error typically falls between 4% and 8% at the 95% confidence level. Review your data for each angle to determine whether the margin of error is within an acceptable range. Report with numerical values, whether your data for each angle is within an acceptable margin of error. Can you help explain what my data means in terms of the standard deviation and the ME?
