Question

A wheel with diameter 32 inches completes four revolutions in 0.5 seconds.

Find the linear speed of the edge of the wheel in inches per second.

Round to the nearest whole number.

Linear speed = inches/s

Yefim S. · Accepted Answer

Linear speed v = ωr, ω is angular speed, ω = 2πn/t. So v = 2πrn/t = 2π·16inch·4/0.5s = 256π inch/s =695.88 inch/s
