A student performed the experiment using the set up you used in the Projectile Motion lab. She got the following values.

Height of flight: 0.611 0.001 m t

23corr: 0.329 0.002 s

Slope of X vs. t23corr: 0.982 0.007 m/s

Slope of H vs. (t23corr)2: 5.65 0.08 m/s2

(a) Use the uncertainty in the slope of the X vs. t23corr graph to propagate the error in the horizontal range for your experiment. (Enter your answer to at least three significant figures.)

X = m

(b) Use the uncertainty in the slope of height of flight vs. (t23corr)2 graph to calculate the error in your experimental value of gravitational acceleration. (Enter your answer to at least three significant figures.)

gexp = m/s2

(c) Report horizontal range and experimental gravitational acceleration with their uncertainties in the correct format.

X X = m

gexp gexp = m/s^(2)
