Question

Body moves on a circular path of radius 1m. it completes one circle in 2 seconds. find its speed

Answer 1

Answer:-

Given:-

• Radii of the path = 1m
• Time taken (t) = 2s

To Find:-

Speed of the particle.

_________...

We know,

v = (2πr)/t

where,

• v = Velocity,
• 2πr = Circumference of the path &
• t = Time taken &
• r = Radii

Therefore,

v = 2π1/2s

➤ v = 2π/2s

➤ v = 1π/s (Correct Answer)

➤ v ≈ 22/7 s (Approx.)

Therefore, the particle took 22/7 seconds.

Answer 2

Answer:

$\huge\tt\bold\blue{Solution-}$

Body moves on a circular path of radius 1m. it completes one circle in 2 seconds. Find its speed.

Given,

Radius = 1 m

Time taken = 2 s

As body is moving on circular path so,the distance'll be equal to the circumference of the circle.

Total Distance travelled by the body =

$2\pi \: r = 2 \times 3.14 \times 1m = 6.28m$

Now,We have-

Distance = 6.28 m

Time = 2 s

Speed =?

$\tt\ {speed = \frac{distance}{time \: taken}}$

$\tt\ {speed = \frac{6.28}{2}}$

$\tt\ {speed = 3.14m/second \: or \: \frac{22}{7}} m/second$
