A 60-cm-diameter wheel is rolling along at 20 m/s. What is

Step 1 of 2

For the given wheel of diameter \(d=60 \mathrm{mrolling}\) with speed \(v_{c m}=20 \mathrm{~m} / \mathrm{s}\), we need to calculate the speed at the point in the forward edge of the wheel as shown in the figure below,

Given data,

Diameter, \(d=60 \mathrm{~cm}=0.6 \mathrm{~m}\)

Rolling speed, \(v_{c m}=20 \mathrm{~m} / \mathrm{s}\)

To find,

speed at the point in the forward edge of the wheel, \(v=?\)
