Answer:

<u>Valterri's unit rate for Day 1 in minutes per lap is 3.5 or 3 minutes and 30 seconds.</u>

Step-by-step explanation:

Let's find Valterri's unit rate for Day 1 in minutes per lap, this way:

Total time = 1 hour, 13 minutes, and 30 seconds

Total time = 60 minutes + 13 minutes + 30 seconds

Total time = 73 minutes and 30 seconds

Total time = 73.5 minutes (30 seconds = 0.5 minutes)

Number of laps = 21

Valterri's unit rate for Day 1 in minutes per lap = Total time/Number of laps

Valterri's unit rate for Day 1 in minutes per lap = 73.5/21

<u>Valterri's unit rate for Day 1 in minutes per lap = 3.5</u>

Objects A and B are in harmonic motion modeled by
Zepler [3.9K]

Answer:

The phase difference between yA and yB is  \frac{-\pi }{12}

Step-by-step explanation:

Given harmonic modeled as :

yA = 8 sin(2t  - \frac{\pi }{3})         And

yB = 8 sin(2t  - \frac{\pi }{4})

The function as written as :

y = a sin(ωt  - Ф)  where  Ф is phase difference

So , phase difference between yA   and  yB = ( Ф_1 - Ф_2 )

Or phase difference between yA   and  yB = ( -  \frac{\pi }{3} + \frac{\pi }{4} )

Or, phase difference between yA   and  yB = (\frac{-4\pi +3\pi }{12})

I.e phase difference between yA   and  yB =\frac{-\pi }{12}

Hence The phase difference between yA and yB is \frac{-\pi }{12}   Answer
