Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 7.9 mi/h , the time to go one mile decreases by 13 s What was your original speed? Express your answer using two significant figures.
While riding on a bus traveling down the highway, you notice that it takes 2.1 min to travel from one roadside mile marker to the next one. A-What is your speed in mi/h? B-How long does it take the bus to travel the length of a football field?
The acceleration of automobiles is often given in terms of the time it takes to go from 0 mi/h to 60 mi/h. One of the fastest street legal cars, the Bugatti Veyron Super Sport, goes from 0 to 60 in 2.40 s. To the nearest integer, what is its acceleration in m/s2?
6) An auto manufacturer advertises that their car can go "from zero to sixty in eight seconds." This is a description of what characteristic of the car's motion? A) instantaneous speed B) displacement C) average speed D) instantaneous acceleration E) average acceleration 7) A light-year is the distance that light travels in one year. The speed of light is 3.00 x 108 m/s. How many miles are there in one light-year? (1 mi = 1609 m, 1 y = 365...
Please answer 6&7 al 6. You are driving home on a weekend from school at 55 mi/h for 110 miles. It then starts to snow and you slow to 35 mi/h. You arrive home after driving 4 hours and 15 minutes.

Suppose you are driving a car in a counterclockwise direction on a circular road whose radius is r 28 m/s (about 63 mi/h) 385 m (see the figure). You look at the speedometer and it reads a steady T(decreasing) (a) Constant angular speed (b) Decreasing angular speed Concepts (i) Does an object traveling at a constant tangential speed (for example, vT= 28 m/s) along a circular path have an acceleration? Yes No (ii) Is there a tangential acceleration aT when...
Two cars drive on a straight highway. At time t=0, car 1 passes mile marker 0 traveling due east with a speed of 20.0 m/s . At the same time, car 2 is 1.1 km east of mile marker 0 traveling at 28.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 0.30 m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.40 m/s2. At what time do the cars pass next...
Two cars drive on a straight highway. At time t = 0, car 1 passes mile marker 0 traveling due east with a speed of 24.0 m/s. At the same time, car 2 is 1.2 km east of mile marker 0 traveling at 30.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 2.8 m/s^2, and car 2 is slowing down with an acceleration of magnitude 3.0m/s^2. At what time do the cars pass next to...
