What is a standard? Does it's value count in determining the number of significant digits in the answer?

The standard deviation is a measure of the dispersion of a series of data

Result = x_{average} ± σ

Explanation:

The standard deviation is a measure of the dispersion of a series of data, it is generally used when a series of measurements of some parameters are made and it is desired to take into account the statistical fluctuations of these measurements, its formula is

where N is the number of measurements

This is a measure equivalent to the absolute error in a single measurement.

Therefore, the number of decimal places in a result must not be greater than the standard deviation.

         Result = x_{average} ± σ

i would say the answer is food.

hope this !

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
