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:
Initially its moving with tail wind so here the speed of wind will support the motion of the plane
so we can say
now when its moving with head wind we can say that wind is opposite to the motion of the plane
now by using above two equations we can find speed of palne as well as speed of wind
