Define: instantaneous velocity.
What is meant by the term “at rest”?
What was the average velocity (in m/s)
of a runner who ran a 5 km marathon in 4 h 40 min 21 sec?
A paramecium named Clyde is traveling down
the 7.5 meters of an average human intestine from the stomach. It
is only moving at 3.5 mm/s, so how long will it take to pass through on
A car is moving at 120.0 km/hr for 15 minutes.
How far will it travel in that time?
Consider a position – time graph:
a. How do you calculate slope of a line?
b. What would the units of the slope be?
c. What does the slope represent?
d. What is indicated by a straight versus
a curved line?
Consider the following paragraph:
Mary travels for 30 minutes at 75 km/h. She then stops for 15 minutes for gas and a souvenir at the gift shop before resuming her trip at 100 km/h. Only 15 minutes later she remembers her sun glasses at the gas station and turns back. She goes back at 100 km/h and picks them up.
a. Diagram this trip in a position – time graph.
b. What was her displacement from when
c. How long did the trip last so far?
d. What was her average velocity?
