Answer #1

Diameter of wheel =50cm=0.5 m

Radius of wheel=r=0.25 m

Revolutions per minute=6000 rpm

Revolutions per second=6000/60=f=100 rps

We know tagential speed is given by

where r is radius of wheel

w is angular frequency(angular speed) which is =

This is tagential speed of grinding wheel
