You are driving your car at a constant speed of 60 miles per hour. What is the speed (in miles per hour) of a point at the very top of your tire? The radius of your tires is 1 ft. what is the speed (in miles per hour) of a point at the very bottom of your tire in contact with the road?
You are driving your car at a constant speed of 60 miles per hour. What is the speed (in miles per hour) of a point at the very top of your tire? The radius of your tires is 1 ft.
Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). Suppose your car averages 31 miles per gallon on the highway if your average speed is 54 miles per hour, and it averages 29 miles per gallon on the highway if your average speed is 69 miles per hour. Answer parts (a) and (b) below. a. What is the driving time for a 3000-mile trip if you drive at an...
1a. You are driving down the street at a constant speed of 60mph. Draw a graph of distance versus time over the course of 4 hours. b. How would you use the graph to determine the rate (speed in mph) at which the car is traveling (assuming you did not already know the answer)? Hint: What is the slope for the graph in part A? What does the term slope mean? c. Now draw a new graph (still distance vs....
You are driving down the hill country roads when you come across a hill of radius 16.50 m. The combined mass of you and your car is 1950 kg. How fast do you have to drive over that hill to feel weightless? What is that speed in miles per hour?
