A bicycle wheel with a radius of 30 centimeters makes a full revolution in 0.2 Find the linear speed of the bicycle.

The linear speed of the bicycle is calculated using the following formula:

V = ω * R, where, according to the condition, the radius of the bicycle wheel is R = 30 cm or 0.3 m.

Formula for calculating the angular speed of a bicycle wheel:

ω = 2Π / Т, where Т is the period; the time during which the bicycle wheel will make one complete revolution (T = 0.2 s).

V = 2ΠR / T.

Let’s perform the calculation:

V = 2 * 3.14 * 0.3 / 0.2 = 9.42 m / s.

Answer: The linear speed of the bike is 9.42 m / s.
