Q1.) What is the distance ran by the GBS cross-country team if they begin at the school and run a 10 mile loop finishing back at the school?
Q2.) In graduate school, I drove 1080 mi from school to home for the holidays. If the trip took 16 h, what was my average speed?
Q3.) If a racecar driver does 200 laps on a 2.5 mile track, what is the displacment of the driver from the start line to the finish line?
Q4.) A car traveling north with a velocity of 25 m/s slows down to a velocity of 15 m/s within 5 seconds. What is the car’s acceleration?
Q5.) If the average speed of a car is 45 km/h, how far can it travel in 40 min?
Q6.) Falling objects drop with an average acceleration of 9.8 m/s2. If an object falls from a tall building, how long will it take before it reaches a speed of 49 m/s?
Q7.) What is meant by a freely falling object?
Group of answer choices
An object under only the influence of gravity
An object moving downward due to gravity
A falling object such as a skydiver with an open parachute
An object moving straight down (1-D motion only)
Q8. a) What is the velocity acquired by a freely falling object 5.0 seconds after it is dropped?
Q8. b) What is it after 6.0 seconds?
Q9.) What is the acceleration of a freely falling object 2 seconds after it has been released from a height of 100 m?
