• Slides: 19 A cross-country skier moves from location A to location B to location C to location D. Each leg of the back-and-forth motion takes 1 minute to complete; the total time is 3 minutes. The unit of length is meters. Calculate the average speed of the skier. KC 3 A cross-country skier moves from location A to location B to location C to location D. Each leg of the back-and-forth motion takes 1 minute to complete; the total time is 3 minutes. The unit of length is meters. Calculate the average velocity of the skier. KC 3 A bicyclist travels 60. 0 km in 3. 5 hours. What is the cyclist’s average speed? KC 6 How much time would it take for the sound of thunder to travel 1, 500 meters if sound travels at a speed of 330 m/s? KC 6 A snail can move approximately 0. 30 meters per minute. How many meters can the snail cover in 15 minutes? KC 6 A car speeds up from rest to 16 m/s in 4 seconds. Calculate the acceleration KC 7 A car slows down from 32 m/s to 8 m/s in 4 seconds. Calculate the acceleration. KC 7 A care is moving eastward along Wildcat Drive and increasing its speed from 25 mph to 45 mph. Which direction is the acceleration? A. B. C. D. North South East West KC 4 A northbound car skids to a stop to avoid a reckless driver. Which direction is the acceleration? A. B. C. D. North South East West KC 4 An Olympic diver slows down after splashing into the water. Which direction is the acceleration? A. B. C. D. Left Right Up Down KC 4 The moving man is moving in the positive direction and speeding up. Which direction is his acceleration? A. Positive B. Negative A gazelle can accelerate at a rate of 6 (m/s)/s for a brief period of time as it tries to elude a hungry bear. If the gazelle starts from rest, how fast is it going after 3 seconds? A cheetah can accelerate at a constant rate of 12 (m/s)/s. If the cheetah accelerates for 5 seconds, starting from rest, how far does it travel? Ima Hurryin is approaching a stoplight with a velocity of 30 m/s. The light turns red and Ima applies the brakes and skids to a stop. If Ima’s acceleration is 6 (m/s)/s, determine the displacement of the car during the skidding process? Describe the motion of the following position vs. time graph: A. B. C. D. E. F.
