What is the distance I traveled? What is: 13 m I travel 35 meters east then 15 meters west. What is my displacement? What is: 20m east I walk 20km north and 15 km west. What is the magnitude of my displacement? What is: 5km I jog 348m south then 145 m east. What is the magnitude and direction of my displacement? 377m E of W I fly 300km North, 150km west, then 100km north. What is the magnitude of my displacement? What is: 427.2km The distance vs. time graph for an object Moving with a constant, Positive velocity. The velocity vs. time graph for an object moving at a constant positive velocity The distance vs. Time graph for an object That is speeding up The position vs. time Graph for an object Slowing down The velocity vs. time Graph for an object Speeding up then Moving at a constant speed An object starting from rest reaches a speed of 48m/s in 6 seconds. What is its acceleration? What is: 2 8m/s An object moving at 6m/s accelerates at 2 4m/s for a distance of 36m. What is the object’s final speed? What is: 18m/s A car moving at 45m/s slams on the breaks and comes to a stop after traveling 90m. What is the deceleration of the car? What is: 2 11.25m/s A car starting from rest reaches a speed of 27m/s after traveling 90m. How long did it take to reach that speed? What is 6.67s A motorcycle moving at 34m/s slams on the breaks and comes to a stop leaving 75m long skid marks on the road. How long does it take the motorcycle to stop? What is: 4.4s position (m) 20 15 10 5 0 0 5 10 15 time (s) What is the speed of the object during the first 5 seconds?

What is: 2 2m/s My motorcycle covers 350m in 10 seconds. What is the speed of my motorcycle? What is: 35m/s My car moves at 24m/s for 3 hours. How far has the car gone? What is: 259,200m or 259.2km How long does it take a lion that can run 32m/s to travel 500m? What is: 15.6s A toy car is moving at 4m/s for 20 seconds then at 2.5m/s for 12 seconds. How far does the car go in total? What is: 110m If you have a 1.3km walk to school and you walk at an average speed of 3m/s the entire way, how many minutes does it take you to get to school? What is: 185m/s Category: Translate it Make your wagers During a 100m sprint, the runner accelerates for to first 2 5 seconds at 1.2m/s then maintains a constant speed for the remainder of the race. How long does it take the runner to finish the race and how fast is she moving when she crosses the finish line? What is: 19.2 seconds and 6m/s
