Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance and time according to this function v(t, x) = x/t. Your measured distance and time have the following values and uncertainties x = 7.5 meters, delta x space equals space 1.4 meters and t = 2.9 seconds and delta t space equals space 1 seconds. What is the uncertainty in the average speed, delta v ?

delta of velocity is 1.558 m/s

Step-by-step explanation:

The main problem is to determine degree of association with the rule of rounding and errors calculation. As out main equation includes division, the following rule can be applied:

where ev- delta v, ex- delta x, et- delta t

As a result, we need to calculate the worst case scenarios: maximum distance over minimum time and minimal distance over the largest time to get maximum and minimum velocity:

Then, we can calculate the value of velocity and its error:

Note, that delta t was used as 1 s.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
