Question

a cyclist goes once round of circular track of diameter 14 meters in 22 sec hus speed is

Answer 1

Answer:

Explanation:

To calculate the speed, you have to make use of the formula and it gave diameter and speed

 Given:

 Diameter is 105 m

Radius: 52.5 m

 Circumference will be

 2x22=44

=44/7

= 6.2

=6.2 x52.5

 = 330 m

 Time is 5 min

=5x60- 3000 seconds

Formula:

 Speed=distance based on time =330/300

=1.1m/s

Answer 2

Answer:

speed+ 1.999m/s

Explanation:

total dist, covered = circumference of track

                           S = 2πr

                           S = 43.98 m

                 time = t = 22 sec.

                   speed is = S/t = 43.98/22=1.999m/s
