a. what is the car's highest possible speed, in kilometers per hour, when the speedometer reads 94km/h?
b. what is the car's lowest possible speed, in kilometers per hour, when the speedometer reads 94km/h?
Percentage uncertainty formula give as
% = [ (delta v)/v] * 100
Delta v = 4.4*94/100 = 4.13 km/h
a) highest possible speed = 94 + 4.13 = 98.13 km/h
b) lowest possible speed = 94 - 4.13 = 89.87 Km/h

(a) A car speedometer has a 6% uncertainty. What is the range of possible speeds when it reads 80 km/h? km/h (lowest) km/h (highest) (b) Convert this to miles per hour. mi/h (lowest) mi/h (highest)
A car speedometer has a 4% uncertainty. What is the range of possible speeds (in km/h) when it reads 60 km/h?
The speedometer readings in passenger cars are based on angular speed of the car's tire axle. Because car's tires are filled with air [typically to the pressure of about 30 psi (pounds-square-inch)], the actual tire radius can be a bit different depending on the air temperature. You want to understand the impact of the air temperature on the tire radius and thus on the accuracy of the speedometer reading based on the ideal gas law. To simplify the calculation, you...
Hassan is sitting in a car moving along the highway. He reads 90km/h on the speedometer 4. a. b. c. What does the reading of the speedometer indicates? Convert the speed given into m/s 10 minutes later the speed of the car was still 90 km/h. We plotted a graph showing the variation of speed with time i. Is the speed of the car constant? Increasing or decreasing? ii. What is the type of motion in this case? Speed d....

6. A construction zone on a highway has a posted speed limit of 40 Kilometers per hour. The speeds of the vehicles passing through this construction zone are normally distributed with a mean of 46 kilometers per hour and a standard deviation of 4 kilometers per hour. Find the percentage of vehicles passing through this construction zone that are: a) exceeding the posted speed limit b) traveling at speeds between 50 and 57 kilometers per hour. 7. A machine at...
