Electrical saw with linear speed

[Robertoalva]

1. A 23 cm diameter circular saw blade spins at 3800 rpm. How fast would you have to push a straight hand saw to have the teeth move through the wood at the same rate as the circular saw teeth?

Homework Equations

v=wr
τ=Iα
τ=rFsinθ

The Attempt at a Solution

tried to multiply the rmp by the radius of the circular saw, but didn't give me a correct answer

Could you show us your working.
(Did you remember to use rad/s for the angular speed?)

I already solved it thank you C:
