Average Velocity Practice Problems
On an ordinary day, you walk from the Park to the Recreational Center at an average speed of 5.4 kph (kilometers per hour), and the round trip takes you 1 h and 30 min. One day, instead of walking, you decide to jog, hence increasing your speed to 10 kph. How much longer does one trip take?
A rushing ambulance which is carrying an injured patient is approaching the hospital with a distance from the hospital defined by x(t) = bt2 - ct3, where b = 3.10 m/s2 and c = 0.147 m/s3. Determine the average velocity of the ambulance for t = 0 to t = 7.0 s.
A dog has escaped from its cage and has run 8.2 km away towards a park. The dog has returned to its cage after it has escaped. The dog has taken 25 minutes to run from the park back to the cage. If the origin is positioned at the cage and the dog has run towards the +x-axis, what was the dog's average velocity in m/s for its return from park to the cage?
During your lunchtime in school, you decided to go out and went 70 m south to a coffee shop, and ordered your favourite coffee. Then you walked 40 m due north to a park, where you sat and enjoyed your coffee. It took you 55.0 s to walk from the school to the coffee shop and then 72.0 s to walk from the coffee shop to the park. Determine your average velocity and average speed for the duration of your lunch break. Consider the motion in the south direction to be positive.
