A bucket is raised from a well by means of a rope that is wound around a wheel of diameter 77 cm.

Given that the bucket ascends in 1 minute 28 seconds with a uniform speed of 1.1 m/sec, calculate the

number of complete revolutions the wheel makes in raising the bucket.

Answer:

It is given that

Diameter of wheel = 77 cm

So the radius of the wheel = 77/2 cm

We know that

Circumference of wheel = 2πr

Substituting the values

= 2 × 22/7 × 77/2

= 242 cm

"hello and welcome my dear students
i am rishikurana the match with leader
and i'm here
the new question it is a bucket is
raised from a well
by means of a rope that is
that is around a wheel of diameter 77
centimeter given that the bucket ascends
in one minute 28 seconds with a uniform
speed of
1.1 meter per second calculate the
number of complete revolutions the wheel
makes
in the raising the bucket
before actually getting into the
question let's look at the few important
points of the question
so in this question we have been given
that the wheel has a diameter of
77 centimeter
whereas the bucket ascends in one minute
28 seconds
with a uniform speed of 1.1 meter per
second and we are supposed to calculate
the
number of revolutions
so let's look at the solution
so we have been given the diameter i am
writing d for diameter
so diameter field is nothing but 77
centimeter
which means at the radius r
is nothing but 77 by 2
centimeter if we convert into meters
we get 77 by 200
meters
also we know that the circumference
circumference
of circle is equals to
2 pi r
now substituting the values we get 2
into 22 by 7
into r which is 77 by 200
solving which we get the answer as 2.4
to meters now also in the question we
have been given
the speed and the time
so i'm writing s for the speed so s that
is speed is given as
1.1 meter per second
whereas the time is given as
writing t for time is given as one
minute
28 seconds which is nothing but
equals to 88 seconds
now if we calculate the total distance
that is covered so we all know that
distance is equal to speed into time
which is nothing but 1.1 into 88
following which we get 96.8
meter as the total distance now to get
the total number of revolutions
i'm adding rev for the revolutions
that is equal to distance
upon circumference
solving which we get
we'll first substitute the value so 96.8
divided by 2.42
we get 40 revolutions as the answer
that means the total number of
revolutions is equals to 40
so i hope my students got this question
