Suppose you are galileo measure the acceleration due to gravity by dropping a canon ball from the tower of pisa, you measure the height of the tower to be h =183 ft, and you estimate that the uncertainty is delta h=0.2 ft. you measure the drop time using your pulse and arrive at delta t =3.5 sec with an estimated uncertainty delta t= 0.5 sec. you perform the experiment just one time. if the formula propagated error is delta g= g (√(delta h/h)^2 +(2* delta t/t)^2) what would you report as your result (including uncertainty) in ft/sec?

It is given that the height of the tower is

The uncertainty the measurement of this height is

Drop time is measured as:

The uncertainty in measurement of time is:

Using the equation of motion: where, is the distance covered, is the initial velocity, is the acceleration and is the time.

(because canon ball is in free fall). we need to calculate the value of a=g.

The uncertainty in this value is given by:

Substitute the values:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
