Answer:
a) 24.43 radians per second
b) 268.73 inches per second
Explanation:
a) The angular speed of the fan on Celsius degrees/second is 1400, so we should convert that value to radians using the fact that 2π rad = 360 °C:
b) Linear speed on a point of the blade is related with angular speed of the fan by the equation
with v linear speed, ω angular speed and r the radius of the blades. So:
Radians isn't really a unity; it is dimensionless so we can put it or not. So:
