A sculptor is sharpening a chisel on grindstone of radius 1.0 m that is spinning with a constant angular speed of 2.0 rad/s.
-What is the tangential speed of a point on the rim of the grindstone?
A)zero m/s
B)0.5 m/s
C)1.0 m/s
D)2.0 m/s
E)4.0 m/s

Question

Quizplus · Accepted Answer

The tangential speed of a point on the rim of the grindstone is given by:
v = rω
where v is tangential speed, r is the radius of the grindstone, and ω is the angular speed.
Plugging in the given values, we get:
v = (1.0 m)(2.0 rad/s) = 2.0 m/s
Therefore, the answer is (D) 2.0 m/s.
