Solved in 1 steps with 5 images
- The pace factor of a random man was recorded to be 0.76 meters per step. If there is 2.7% margin of error with the use of his pace factor, what is the value of the probable error of the distance of a line measured using the man's pace factor if the recorded number of steps is 143.A) What is the time-mean speed? Present your answer in units of [feet/sec] to two decimal places? B) What is the spacing between the vehicles in Image 1? Present your answer to the nearest foot. C) I calculate that the (average) density obtained from these images is 18.2 [veh/mi]. Assume that this value is correct, even if I made a mistake.If a loop detector sensing these vehicles was occupied 5% of the time, what is the average length of the vehicles?
