Answer:
Step-by-step explanation:
We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed of the object in revolutions per minute (rpm) is:
(1)
However, we have to convert this to , since this is the unit used in the International Systme of Units for angular speed.
So, we can do this knowing that:
(2)
Where:
is the value of one revolution
is the period of rotation
With this information in mind, let's make the conversion:
(3)
(4) This is the wind turbine angular speed
Given parameters:
Distance traveled = 1778miles
Average speed = 61.7 miles per hour
Unknown:
Time taken for the travel = ?
Speed is a physical quantity. It is the rate of change of distance with time.
It can be mathematically expressed as;
Speed =
The unknown here is the time taken;
Substitute the parameters and solve for it;
61.7 =
time taken = = 28.8hrs
The time taken is 28.8hrs
