(8) for physical conditioning the soccer team from you school runs 5 times around the track. the track is 440 m long. if it takes the team an average of 1 minute and 35 seconds to complete each lap, what is their average speed and average velocity?

(8) for physical conditioning the soccer team from you school runs 5 times around the track. the track is 440 m long. if it takes the team an average of 1 minute and 35 seconds to complete each lap, what is their average speed and average velocity?

Answer

Answer:

Average speed: $5.18\ m/s$, Average velocity: $0\ m/s$

Explanation:

Step1: Convert time per lap to seconds

1 minute and 35 seconds = $60 + 35=95$ seconds

Step2: Calculate total distance

The team runs 5 laps and each lap is 440 m long. So total distance $d = 5\times440=2200$ m

Step3: Calculate total time

Time for 5 laps $t=5\times95 = 475$ s

Step4: Calculate average speed

Average speed $v_{avg - speed}=\frac{d}{t}=\frac{2200}{475}\approx5.18\ m/s$

Step5: Calculate average velocity

Since the team ends at the starting - point after running 5 laps (displacement $\Delta x = 0$), average velocity $v_{avg - velocity}=\frac{\Delta x}{t}=\frac{0}{475}=0\ m/s$
