Question

Consider a bicycle that has wheels with a circumference of 1 m. What is the linear speed of the bicycle when the wheels rotate at 2 revolutions per second?

Answer 1

Answer:

V= 12.56 m/s

Explanation:

Given that

R= 1 m

The angular speed ,ω = 2 rev/s

We know that 1 rev = 2 π rad

Therefore

ω = 4 π rev/s

The linear speed V is given as

V= ω x R

V = 4 π x 1 m/s

V= 4 π m/s

Therefore the speed of the bicycle will be 4 π m/s

We know that , π = 3.14

V= 12.56 m/s

The linear speed will be 12.56 m/s
