Question

Diameter of a wheel is 6 m. The linear speed of a point on its rim is 33 $m{s}^{-1}$. Then its angular velocity in rpm.

• A. 100
• B. 102
• C. 104
• D. 105

Answer 1

The correct option is D

105

Radius of the wheel (R)=3m
Linear speed of the rim = V = Rw
$\Rightarrow w=\frac{v}{r}=\frac{33}{3}=11\frac{rad}{s}=105\frac{rev}{min}$
