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:

be subject to a force andchange its motion

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
