Answer:

A body travels along a circular path.

Radius of circular path (r) = 50m

Time taken to complete half a revolution (t) = 30s

______________________________

To Find

The body's average velocity and speed.

______________________________

Solution

First, we'll deal with the average velocity.

So let's find the displacement of the body first.

We know that,

Displacement of half circle = Diameter of the circular path

(Diameter = 2 × Radius)

Displacement of the body = 2 × 50

Displacement of the body = 100 m

Average Velocity =

\dfrac{Total \: displacement \: covered}{Total \: time \: taken}TotaltimetakenTotaldisplacementcovered

Average Velocity =

\dfrac{100}{30}30100

Average Velocity =

\dfrac{10}{3}310

Average Velocity = 3.33 m/s

∴ The average velocity of the body is 3.33 m/s

______________________________

Now let's find the distance covered by the body in order to find the average speed.

Distance = Semi-perimeter of circle

Distance = πr

Distance =

\dfrac{22}{7} \times 50722×50

Distance =

\dfrac{1100}{7}71100

Distance = 157.14 m

Average Speed =

\dfrac{Total \: distance \: covered}{Total \: time \: taken}TotaltimetakenTotaldistancecovered

Average Speed =

\dfrac{157.14}{30}30157.14

Average Speed = 5.24 m/s [approx.]

∴The average speed of the body is 5.24 m/s.

∴ The average velocity of the body is 3.33 m/s
