Question

A wheel that has a radius of 70 cm rotates are 5 radians per Second, what is the velocity of the edge of the wheel in Meters per second​

Answer 1

Answer:Radius =70cm

Distance covered in one rotation = circumference of wheel =2πr

=2×

7

22

​

×70

=440cm

Distance covered in 300 rotation =300×440

=132000=

100000

132000

​

=1.32km

Given that distance of 1.32km is covered in 5 minutes or

60

5

​

hour.

Therefore,

Speed of cycle =

1.32×60

​

=15.84km/hr
