Question

suppose one boy is running along the periphery of a circle pf radius 14 m starting from one point pf periphery he reaches the opposite point after 20 sec. i) find the distance travelled by the boy ii) determine its velocity as well as speed​

Answer 1

Answer:

1.Distance travelled by the boy= 44m

2. Velocity= 2.2 m/s

Explanation:

Let boy Start running from point A the opposite points will be B .

1. Distance from A to B = 2πR ÷ 2

                                   =  22/7 * 14

                                    = 44

2. Speed = Distance÷Time

               = 44÷20= 2.2 M/s
