3. An airp

Notes

3. An airplane travels from Calgary to Toronto in 4h 20 min. Find the average speed if the distance between the two cities is 4330 km. [ 1.0x103 km/h ] 4. In a race, a boat travels a distance of 220 m [E 40° N] and then rounds a buoy and travels a distance of 360 m [W] to the finish line. The whole trip takes 22 s. Using either a scale diagram or vector components, determine the displacement and average velocity of the boat. {240 m [N54°W], 11 m/s [N54°W]} 5. 6. 7. 8. 9. A train travelling at 1.00x102 km/h slows down with a uniform acceleration of 0.60 m/s2 . How long does it take to stop? [ 46 s ] A bobsled has a constant acceleration of 2.0 m/s2, starting from rest. a. b. c. d. How fast is it going after 5.0 s? How far has it travelled in 5.0 s? What is the average velocity in the first 5.0 s? How far has it travelled by the time its speed has reached 30.0 m/s? [ 1.0x101 m/s; 25 m; 5.0 m/s; 230 m ] A stone is thrown straight down from the top of a cliff with an initial velocity of 6.0 m/s. It reaches the bottom in 3.0 s. How high is the cliff? [ 62 m ] A plane flying at 80.0 m/s releases a package from a height of 1.00x103 m. Find a. the time it takes for the package to hit the g...
