1.A NASA team oversees a space shuttle launch at Cape Canaveral and then travels to Edward's Air Force Base in California to supervise the landing. Which group of people, the astronauts or the NASA team has the greater displacement? the greater distance? 2.A commuter drives 15.0 km on the highway at a speed of 25.0m/s (56 mph), parks at work and walks 150. m at a speed of 1.50m/s from his car to his office. (a) Determine the total time of the commute. (b) Determine the average speed of the entire commute. (700.s,21.6m/s) 3. The peregrine falcon is the fastest of flying birds (and, as a matter of fact,is the fastest living creature). A falcon can descend with a speed of 2.50times 10^2km/h If a falcon flies at this speed for 2.00 s and then flies another 1.00times 10^2m in 2.50 s, what is the falcon's average speed for the entire flight? (53.1m/s) 4. The black mamba is one of the world's most poisonous snakes and with a maximum speed of 18km/h it is also the fastest. Suppose a mamba waiting in a hide-out sees prey and begins slithering toward it at its maximum speed. After s, the mamba realizes that its prey can move faster than it can The snake then turns around and slowly returns to its hide-out in 12 s. Calculate a. the mamba's average speed. (1.7m/s or 1.8m/s depending on how you round) b. the mamba's average velocity. (0m/s)

1. <br />- Displacement: Astronauts<br />- Distance: NASA team<br /><br />2. <br />(a) Total time of the commute:<br />\[ \text{Time on highway} = \frac{15.0 \text{ km}}{25.0 \text{ m/s}} = 600 \text{ s} \]<br />\[ \text{Time walking} = \frac{150 \text{ m}}{1.50 \text{ m/s}} = 100 \text{ s} \]<br />\[ \text{Total time} = 600 \text{ s} + 100 \text{ s} = 700 \text{ s} \]<br /><br />(b) Average speed of the entire commute:<br />\[ \text{Total distance} = 15.0 \text{ km} + 150 \text{ m} = 15000 \text{ m} + 150 \text{ m} = 15150 \text{ m} \]<br />\[ \text{Average speed} = \frac{15150 \text{ m}}{700 \text{ s}} = 21.6 \text{ m/s} \]<br /><br />3. Falcon's average speed:<br />\[ \text{First segment distance} = 2.50 \times 10^2 \text{ km/h} \times \frac{1000 \text{ m}}{1 \text{ km}} \times \frac{1 \text{ h}}{3600 \text{ s}} \times 2.00 \text{ s} = 138.89 \text{ m} \]<br />\[ \text{Total distance} = 138.89 \text{ m} + 100 \text{ m} = 238.89 \text{ m} \]<br />\[ \text{Total time} = 2.00 \text{ s} + 2.50 \text{ s} = 4.50 \text{ s} \]<br />\[ \text{Average speed} = \frac{238.89 \text{ m}}{4.50 \text{ s}} = 53.1 \text{ m/s} \]<br /><br />4. <br />(a) Mamba's average speed:<br />\[ \text{Total distance} = 18 \text{ km/h} \times \frac{1000 \text{ m}}{1 \text{ km}} \times \frac{1 \text{ h}}{3600 \text{ s}} \times 12 \text{ s} = 60 \text{ m} \]<br />\[ \text{Average speed} = \frac{60 \text{ m}}{12 \text{ s}} = 5 \text{ m/s} \]<br /><br />(b) Mamba's average velocity:<br />\[ \text{Net displacement} = 0 \text{ m} \]<br />\[ \text{Average velocity} = \frac{0 \text{ m}}{12 \text{ s}} = 0 \text{ m/s} \]

Explain

1. Displacement is the shortest distance from the initial to the final position, while distance is the total path traveled. The astronauts have greater displacement (straight up and down), while the NASA team has greater distance (traveling from Florida to California).<br />2. (a) Calculate the time for each segment and sum them. (b) Average speed is total distance divided by total time.<br />3. Average speed is total distance divided by total time.<br />4. (a) Average speed is total distance divided by total time. (b) Average velocity considers the net displacement over time.
