```Physics Review – Uniform Motion, Velocity, Speed
1. Look at the following position vs. time graph, and answer the following questions.
(Assume Positive = East, Negative = West)
a. What is the velocity from 0s-4s?
b. What is the speed from 10s-12s?
c. What is the speed and velocity from 4s – 6s?
2. If a cyclist is traveling East at 14 m/s, how long would it take the cyclist to travel 700 m?
3. A motorboat is traveling at 35 km/hr. How far would the motorboat travel in 10 minutes?
(*HINT: think units. Are they consistent?)
4. A racecar travels 7 km in 4 seconds. What is the velocity of the racecar, in m/s?
(*HINT: think units. Are they consistent?)
Physics Questions – Velocity, Speed, and Unit Conversions Practice
1. Convert 35 km/h to m/s.
2. Convert 3 m/s to km/h.
3. A car’s displacement is 42 km [S] after driving for 0.75 hours. What is the car’s average velocity
in km/h and m/s?
4. A car is traveling forward at 75 km/h. How far does the car travel in 25s?
5. A person paddles a canoe 1.2 km [W] in 0.20 hours.
a. What is the average velocity of the canoe, in km/h?
b. What is the average velocity of the canoe, in m/s?
6. What is the displacement of a car traveling 48 km/h [E] during a 5.0 s time interval?
7. How many seconds would it take a cyclist, traveling at 25 km/h, to travel 75 m forward?
8. A car is traveling at 75 km/h in the forward direction. How many metres forward would the car
travel after 10 minutes?
Physics Review – Uniform Motion, Velocity, Speed KEY
1. Look at the following position vs. time graph, and answer the following questions.
(Assume Positive = East, Negative = West)
d. What is the velocity from 0s-4s?
5 m/s [E]
e. What is the speed from 10s-12s?
~ 10 m/s
f.
What is the speed and velocity from 4s – 6s?
Zero
2. If a cyclist is traveling East at 14 m/s, how long would it take the cyclist to travel 700 m?
T = 700m/ (14 m/s) = 50 seconds
3. A motorboat is traveling at 35 km/hr. How far would the motorboat travel in 10 minutes?
(*HINT: think units. Are they consistent?)
10 minutes = 10/60 hours = ~ 0.17 hours
35(0.17) = 5.8 km
4. A racecar travels 7 km in 4 seconds. What is the velocity of the racecar, in m/s?
(*HINT: think units. Are they consistent?)
7 km = 7000 m; 7000 m/4 s = 1,750 m/s
