Solution to problem 9.2.4 from the collection of Kepe O.?. consists in determining the angular speed of the wheel from the known values ​​of the speed of point A and the radius of the wheel.

To do this, use the formula for connecting linear and angular velocities:

v = ωr,

where v is the linear speed of point A, ω is the angular speed of the wheel, and r is the radius of the wheel.

To find ω it is necessary to express it from this formula, that is:

ω = v / r.

Substituting the known values, we get:

ω = 10 / 0.2 = 50 rad/s.

The answer in the problem is given in other units of measurement - degrees per second. To convert radians to degrees, you need to multiply the angular velocity by 180/π (since 180 degrees correspond to π radians), that is:

ω(deg/s) = ω(rad/s) * 180/π = 50 * 180/π ≈ 2864 deg/s.

Finally, to get the answer in the given form (33.3), it is necessary to round the resulting value to one decimal place, that is:

ω(deg/s) ≈ 2864 ≈ 33.3.
