1. Calculate the speed for a car that went a distance of 125 kilometers in 2 hours. 2. A baseball is thrown a distance of 60meters. What is its speed if it takes 0.5 seconds to cover the distance? 3. How much time does it take for a bird flying at a speed of 45 kilometers per hour, to travel a distance of 1800 kilometers? 4. A comet is cruising through the Solar System at a speef of 50,000 kilometers per hour for 4 hours. What is the total distance traveled by the comet during this time? B. VELOCITY 5. If the velocity of a car is 45km/h west, how far can the car travel in 0.5 hours? 6. What is the velocity of a motorcycle travelling 10km west in 3 hours? 7. How much time does it take a person to walk 12km north at a velocity of 6.5km/h? 8. What is the velocity of a rocket that goes 700km north in 25 seconds? C. ACCELERATION 9. A race cars velocity increased coming out of a turn, from 44m/s to 66m/s in 11 seconds, what is the cars acceleration? 10. Calculate a cars acceleration if its velocity increases from a standstill to 14m/s in 2 seconds. 11. A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4m/s. 3 seconds later, at the bottom of the slope, its speed is 22m/s. What is the cars acceleration? 12. A cyclists accelerates from 0m/s to 8m/s in 3 seconds. a. What is the cyclists acceleration? b. Is the cyclists acceleration higher than that of a car which accelerates from 0m/s to 30m/s in 8 seconds? 13. A car advertisement states that a certain car can accelerate from rest to 70km/h in 7 seconds. Find the cars actual acceleration? 14. You are travelling in a car that is moving a velocity of 20m/s. Suddenly a car 10 meters in from of you slams on its brakes. At that moment, you also slam on your brakes and slow to 5m/s. Calculate your acceleration if it took you 2 seconds to slow down to 5m/s. 1. Calculate the speed for a car that went a distance of 125 kilometers in 2 hours. 2.
