INTRO TO DISTANCE, DISPLACEMENT, SPEED, VELOCITY QUIZ REVIEW
Position of a truck on a trip. Use the graph to answer the questions. Describe the motion of the truck at segments A and B relative to home b a) Segment A (0-6 minutes) Moving away from home a (hundreds) b) Segment B (11 minutes) stopped
Position of a truck on a trip. Use the graph to answer the questions. What is the average speed of the truck between 0-6 minutes? b ? =? ? = 1000? 6 ??? = 166.67 m/min What is the truck s instantaneous speed at 5 minutes? a ? =800 ? 5 ??? = 160 m/min (hundreds) What is the overall average speed of the truck for its entire trip? ? =1,000 ? 11 ??? = 90.91 m/min Time (min)
Julie decides to meet her friends at the park, but she needs to buy a Frisbee before he gets there. So Julie leaves her house and walks 3 miles north to the store to buy her Frisbee, then walks 2 miles south to get to the park to meet her friends. What is the total distance Julie traveled? 3 mi + 2 mi = 5 mi What is Julie s displacement? (you may draw a picture to help you out) 3 mi 2 mi = 1 mi North
What is the difference between speed and velocity? SPEED distance traveled per unit of time VELOCITY speed in a given direction
What is the velocity of a car that travels a distance of 305 miles from Pittsburgh to Philadelphia in 5.6 hours? Given: Formula: ? =? d = 305 mi ? t = 5.6 hr Work Space: ? =305?? 5.6 ? = 54.46 mi/hr Find: Velocity Final Answer: 54.46 mi/hr East
How long does it take a plane to go from Hong Kong to Los Angeles if its speed for the trip is 550 mi/hr and the total distance is 7865 miles? Given: Formula: t =? s = 550 mi ? d = 7865 hr 7865?? 550 ??/ ? = 14.3 hr Work Space t = Find: time Final Answer: 14.3 hr
How far does a person run if they average 14.8 km/hr for a total of 1.2 hours? Given: Formula: s = 14.8 km/hr t = 1.2 hr d = s x t Work Space d = (14.8km/hr)(1.2 hr) = 17.76 km Find: distance Final Answer: 17.76km
