Question

If the particle completes one rotation along a circular track having radius 14 m in 44 seconds then the value of speed it’s speed is​

Answer 1

Answer:

7/22m/s

hope that it is helpful for you thanks

Answer 2

Given:

radius of circular track = 14 m,

Time = 44 seconds.

As we know that, the distance covered by particle along circular track is the circumference of that circle.

Distance = Circumference = 2 × π × r

Distance = Circumference = 2 ×( 22/7 )× 14

Distance = 2 × 22 ×2

Distance = 88 m.

Speed = distance /time.

Speed = 88 / 44

Speed = 2 m/s.

The answer is 2 m/s
