Chapter 2, Problem 11CQ
If you divide the total distance traveled on a car trip (as determined by the odometer) by the time for the trip, are you calculating the average speed or the magnitude of the average velocity? Under what circumstances are these two quantities the same?

An adventure racer ran 1.7 km north, then 3.2 km 63° to the south of due east, then
1.4 km west. She completed the trip in 2 hr: 5 min :8 s. What was the magnitude of
her average velocity over the entire trip in m/s?
Express your answer in metres/second to two decimal places (do not include units in
your answer).
A stone thrown downward with an initial velocity of 44.1 m/sec will travel a distance of S meters, where s(t)=4.9t^2 +44.1t and t is in seconds. If a stone is thrown downward at 44.1m/sec from a height of 343 m, how long will it take for the stone to hit the ground ?

We can do this by approximating the area under a curve. But what curve? In this case, imagine that the velocity of the vehicle is a function of time, v(t). We do not have this function, but we do have the values of th function at certain points in time. If we assume the function (the velocity) is constant between these points in time (which is not actually true), we can get an approximation. distance traveled - feet Give another estimate using the velocities at the end of the time periods. distance traveled feet Question Help: Video 20210110 2205M2 ing 20210110 220552 jpgarrow_forward
