Suppose you collected a data set in which you measured fall-times for different fall-heights. You plotted the data and fit the mathematical model, y = Ax2, to match the physical hypothesis, y = 1/2*g*t2. From the best-fit curve, you are told that the value of your fit-parameter, A, is 4.6 m/s2 ± 0.4 m/s2. Determine the value of g ± (delta)g for this fit-parameter value.
We would like to be able to make meaningful interpretations of variations in the
acceleration due to gravity, g, as small as 0.1 mgal. How accurate must our knowledge
of the latitude of our gravity stations be? (A “gravity station" is just a location at which
you make a gravity measurement.) You can assume your latitude is 45°.
From a launch tower located at point B, a rocket goes into space with a velocity ? (ℎ) = 3ℎ + 2 in miles / s, where h is the height of the rocket relative to the earth in miles. The liftoff is monitored from a station located at A 844,626 miles from station B. How long does it take for the rocket to be initially registered by the instruments on the horizon of A? Consider the radius of the earth as 3650 miles.

- Using a telescope, you track a rocket that was launched 13 km away recording the angle ? between the telescope and the ground at half‑second intervals. Estimate the velocity of the rocket if ?(10)=0.205 and ?(10.5)=0.225. (Give your answer in kilometers (km) per hour (h) and round to one decimal place.)arrow_forwardA drone is flying at 162 kilometers per hour at a constant altitude of 3 km above a straight road. The drone pilot uses radar to determine that an oncoming motorcycle is at a distance of exactly 4 kilometers from the drone, and that this distance is decreasing at 245 kilometers per hour.
