6. KAP #1 Study Significant Figures from your book on your own. Answer the following questions: pg. 19 9,10,11,13,14 Come on Tuesday ready to ask questions (We do not have time to spend a whole class on them, so when studying significant figures you should be able to answer the following questions if you’ve done a good job. 1.What are they? What does the book mean by a significant figure? 2.When are significant figures used? 3.What benefits do using significant figures give to scientists and science students? 4.How are they used? (How do you use them in problem solving?)

7. KAP #2 1.The fastest fish, the sailfish, can swim 1.2x10 2 km/h. Suppose you have a friend who lives on an island 16 km away from the shore. If you send a message using a sailfish as a messenger, how long will it take for the message to reach your friend? 2.An ostrich can run at speeds of up to 72 km/h. How long will it take an ostrich to run 1.5 km at this top speed? 3.A cheetah is know to be the fastest mammal on Earth, at least for short runs. Cheetahs have been observed running a distance of 5.50x10 2 m with an average speed of 1.00x10 2 km/h. a.How long would it take a cheetah to cover this distance t this speed? b.Suppose the average speed of the cheetah were just 85.0 km/h. What distance would the cheetah cover during the same time interval calculated in (a)? 4. The peregrine falcon is the fastest of flying birds (and, as a matter of fact, is the fastest living creature). A falcon can fly 1.73 km downward in 25 s. What is the average velocity of the peregrine falcon?

9. KAP #4 CONSTANT ACCELERATION PROBLEMS 1.In 1986, the first flight around the globe without a single refueling was completed. The aircrafts average speed was 186 km/h. If the ariplane landed at this speed and accelerated at -1.5 m/s 2, how long did it take fo the airplane to stop? 2.Some tropical butterflies can reach speed of up to 11 m/s. Suppose a butterfly flies at a speed of 6.0 m/s while another flying insect some distance ahead flies in the same direction with a constant speed. The butterfly then increases its speed at a constant rate of 1.4 m/s 2 and catches up to the other insect 3.0 s later. How far does the butterfly travel during the race? 3.Stetching 9345 km from Moscow to Vladivostok, the Trans-Siberian reailway is the longest single railroad in the world. Suppose the train is approaching the Moscow station at a velocity of +24.7 m/s when it begins a cosntant acceleration of -0.850 m/s 2. This acceleration continues for 28s. What will be the trains final velocity when it reaches the station.

11. REPRESENTING VELOCITY AND ACCELERATION GRAPHICALLY Step 1: Repeat 2 of your most recent labs with slight modifications. a) Tumblebuggy speed lab b) Penny drop gravity lab Modifications: Track the position of the car and penny as they move. You can do this using the lap feature on your phone. Do multiple trials and average them for better data. Step 2: Record your data in tables. Create your own. In each table begin with displacement (m), time (s) Step 3: Pick 5 points on your best fit curve of your displacement vs time graph and find the instantaneous velocity at that instant (slope of the tangent line). Step 4: Graph velocity vs. time. Step 5: Pick 5 points on your best fit curve of your velocity vs. time graph and find the instantaneous velocity at those points (slope of the tangent line) Step 6: Graph Acceleration vs. time Hint: You can check your work if you have a graphing calculator and you enter your displacement vs time data.

Suppose a resident accidentally causes a chunk of ice to fall from the roof. What would be the velocity of the ice as it hits the ground? Neglect Air resistance. 2.Brian Berg of Iowa built a house of cards 4.88 m tall. Suppose Berg throws a ball from ground level with a velocity of 9.98 m/s straight up. What is the velocity of the ball as it first passes the top of card house? 3. The tallest roller coaster in the world is the Desperado in Nevada. It has a lift height of 64 m.
