Sorry if i have mistakes in text, i'm from russia tho
The answer to the question is B
Angular acceleration is change of angular velocity over time:
α = 5 / 8 = 0.625 rev / s²
Number of revolutions of the 1st part:
α · t² /2 = 0.625 * 8² / 2 = 20 rev.
The 2nd part:
α = 5/12 = 0.41667 rev/s²
5 * 12 - ( 0.41667 * 12² / 2 ) = 60 - 30 = 30 rev.
In total: 20 + 30 = 50 revolutions
Answer:
The time will be 10:42:40 am. = 10:42 am.
Step-by-step explanation:
∵ The time of 10 questions = 10 × 30 = 300 sec. ÷ 60 = 5 min.
∵ The time of 15 questions = 15 × 40 = 600 sec. ÷ 60 = 10 min.
∵ The time of 12 questions = 12 × 2 = 24 min.
∵ The total of the questions = 10 + 15 + 12 = 37
∵ The time of total rests between the questions = 36 × 5 = 180 ÷ 60 = 3 min.
* Note: (The rests time less than the number of questions by 1 because there is no rest after the last question)
∵ The time of sharpens = 2 × 20 = 40 sec. ÷ 60 = min.
∴The total time of the test = 5 + 10 + 24 + 3 + = min.
