The Wheel Of A Motorcycle Is Of Radius 35 Cm. The Number Of Revolutions Per Minute Must The Wheel Make So As To Keep A Speed Of 66 Km/H Is

Given:

The radius of a wheel, r = 35 cm = 0.35 m.

The speed it must keep, s = 66 km/h =\( \frac{66 * 1000}{60} m/min = 1100 m/min \)

The number of revolutions, n it makes per minute to maintain that speed.

The circumference of the wheel, C = \( 2\Pi r = 2 * \frac{22}{7} * 0.35m = 2.2 m. \)

The distance the wheel covers in 1 min, d = 1100 m.

Now the distance covered by a wheel in one revolution = the circumference of the wheel.

Therefore, the number of revolutions, n = \( \frac{d}{C} \) \( \Rightarrow \frac{1100}{2.2} \) \( \Rightarrow 500 \)
