Diameter of a wheel is 6 m. The linear speed of a point on its rim is 33 ms−1. Then its angular velocity in rpm.
Radius of the wheel (R)=3m Linear speed of the rim = V = Rw ⇒w=vr=333=11rads=105revmin
A wheel is of diameter 1m. If it makes 30revolutions/sec, then the linear speed (in m/sec) of a point on its circumference is:
