What is the velocity in inches per second of a roll that has a speed of 140 rpm and a diameter of 2.4 cm?
fgiga [73]

Answer:

The velocity in the border of the roll is 0.025 m/s.

Step-by-step explanation:

We have a roll that has an angular velocity of

\omega = 140\, rpm

The tangent velocity (of the edge of the roll) can be calculated as

V=\omega * r=\omega * D/2\\\\V=(1/2)*140\frac{1}{min}*2.4\, cm*\frac{1m}{100cm}*\frac{1min}{60s}\\\\V=0.028\,m/s

The velocity in the border of the roll is 0.025 m/s.
