Final answer:
The angular speed of a wheel 213 cm in diameter with a period of 2.35 s for each revolution is approximately 2.67 rad/s.
Step-by-step explanation:
To find the angular speed of the wheel in radians per second (rad/s), we use the given period of 2.35 s for one revolution. Since one revolution is 2π radians, the angular speed ω can be calculated by dividing the angle in radians by the time period.
ω = Θ / t = 2π rad / 2.35 s
Therefore, the angular speed of the wheel is approximately ω = 2.67 rad/s.
