Exam 27: Velocity

A car accelerates in a westerly direction from a yield sign to a constant speed on the freeway.It then exits the freeway and parks.Measure the location of the car as its distance west of the yield sign.Make a graph of velocity.Be sure to label you graph appropriately. ​ ​ ​ ​ .

An airplane leaves New York and flies south at a constant speed to Miami, where it lands and takes on new passengers.It then makes the return flight at a constant speed.Make a graph that shows distance north of Miami over the period of the round-trip flight.Be sure to label your graph appropriately. ​ ​ ​ .

A man hikes up a mountain to the peak, where he rests for a few minutes and then continues down the other side of the mountain.We measure his location as distance up from the base of the mountain.What can be said about the man's velocity when he is hiking up the mountain?

When a rock is tossed upward, its velocity at the peak of its flight is 0.

An airplane leaves New York and flies south at a constant speed to Miami, where it lands and takes on new passengers.It then makes the return flight at a constant speed.Make a graph that shows distance south of New York over the period of the round-trip flight.Be sure to label your graph appropriately. ​ ​ ​ .

When the graph of directed distance is a horizontal line above the horizontal axis, what can be said about the graph of velocity?

When velocity is 0, what can be said about directed distance?

An airplane leaves New York and flies south at a constant speed to Miami, where it lands and takes on new passengers.It then makes the return flight at a constant speed.The graph of distance north of Miami is shown.Make a graph of velocity for the round-trip.Be sure to label your graph appropriately. ​ ​

The graph of velocity lies above the horizontal axis.What can be said about the graph of directed distance?

You leave your apartment at 10:00 am and take a leisurely stroll to get lunch at a pizza place that is 2500 yards west of your home.You have lunch there from 12:00 to 1:00 pm.You return home, arriving at 2:00 pm, and take a one-hour nap.Then you go to a friend's house, which is east of your home.You stay there from 4:00 pm on.Make a graph of distance west from your home versus time.Be sure to label your graph appropriately.

A basketball is tossed onto the hardwood, where it bounces several times.We measure its location as distance down from the ceiling.When the ball is at the peak of its bounce, what can be said about its velocity?

A basketball is tossed onto the hardwood, where it bounces several times.We measure its location as distance down from the ceiling.When the ball is moving downward, what can be said about its velocity?

A rock is tossed upward from the ground.The graph of distance up is shown.Make a graph of velocity. ​ ​​

A rock is tossed upward from the ground.It rises and then falls back to the ground.Sketch a graph of distance up from the ground.Be sure to label clearly your graph.

An airplane leaves New York and flies south at a constant speed to Miami, where it lands and takes on new passengers.It then makes the return flight at a constant speed.The graph of distance south of New York is shown.Make a graph of velocity for the round-trip.Be sure to label your graph appropriately. ​ ​

A basketball is tossed onto the hardwood, where it bounces several times.We measure its location as distance down from the ceiling.When the ball is moving upward, what can be said about its velocity?

When directed distance is increasing, velocity is negative.

A car accelerates in a westerly direction from a yield sign to a constant speed on the freeway.It then exits the freeway and parks.The graph of velocity is shown below.Make a graph of distance west of the yield sign.Be sure to label you graph appropriately. ​ ​ ​

A man leaves home driving west on a straight road.We locate the position of the car as the distance west from home.Suppose the man begins his trip and sets his cruise control, but after a few minutes he notices that he has forgotten his wallet.He returns home, gets his wallet, and then resumes his journey.He figures that he may be late, so he sets the cruise control a little higher than before.The graph of distance west from home is shown.Make a graph velocity for the trip. ​ ​

A car is driving north at a constant velocity of 56 miles per hour.Since velocity is constant, distance north, in miles, is a linear function.What is the slope of this linear function? ​
