4. What does the symbol ∆ mean?
5. Anne and Steve walk eastward with a speed of 0.98 m/s. If it takes them 34 minutes to walk to
the store, how far have they walked?
6. If Dannika rides south on her bicycle in a straight line for 15 minutes with an average speed of
12.5 km/h, how far has she ridden?
7. Sydney drives her car with an average velocity of 48.0 km/h to the west. How long will it take
her to drive 144 km on a straight highway?
8. A bus travels 280 km north along a straight path with an average velocity of 88 km/h to the
north. The bus stops for 24 minutes, then it travels 210 km north with an average velocity of
75 km/h to the north.
a. How long does the total trip last?

9. A car is at a red light. When the light turns green, the car increases its velocity from rest to
31 m/s in 14.7s. What is the car’s acceleration?
10. As a bus comes to a sudden stop to avoid hitting a pedestrian, it accelerates uniformly at
-4.21 m/s2 as it slows from 9.0 m/s to 0 m/s. Find the time interval of acceleration for the bus.
11. A car with an initial speed of 23.7 km/h accelerates at a uniform rate of 0.92 m/s2 for 3.6 s. Find
the final speed and displacement of the car during this time.
12. A car traveling initially at +7.0 m/s accelerates uniformly at the rate of +0.80 m/s2 for a distance
of 245m.
