Airplane propeller The length of the largest airplane propellerever used was 22 feet 7.5 inches. The plane was poweredby four engines that turned the propeller at 545 revolutionsper minute.(a) What was the angular speed of the propeller in radiansper second?(b) Approximately how fast (in mi/hr) did the tip of thepropeller travel along the circle it generated?

As given that propeller turned by 4 engines with N= 545 rpm ;So the angular velocity of the…

Answered: Airplane propeller The length of the…

At rest, the mug is 10 cm deep and 6 cm in diameter, and it holds coffee 7 cm deep. What is the maximum angular rotation she can do in rad/s without spilling her coffee?
Question 3 On a curved road of radius 200m, a biker accelerated from a speed of 80 km/h to 120 km/h in 5 seconds. When the speed of the bike reaches 120 km/h, an object C fly from nowhere and hit the wheel(of the bike), causing an accident. a) What is the total acceleration of the bike before the accident occurred? b) What is the angular velocity of the bike when the accident happened, assuming that the object C entangled itself in the bicycle wheel? The mass of the bike(and biker) is 150 kg while the object C has a mass of 5 kg.

The Wright Brothers designed an engine and propeller that would produce enough forward motion to lift a simple light airplane. The 3 meter diameter blade rotated at a constant 330 rotations per minute (RPM). How does the RPM of the tip of one blade compare to the RPM of the middle of the one blade (halfway towards the center of the propeller)? The RPM is twice as much. The RMP is the same. The RPM is half as much. The RPM is one quarter as much.
Consider a helicopter flying in a straight path at a speed of 52 m/s. The the rotor diameter is 10 m and the rotors are moving at 264 RPM (revolutions per minute). What is the maximum rotor tip speed (in m/s). Hint: Note that the rotor will sometime be moving in the direction of the flight path and at other times opposite to the flight path or at an angle to the flight path. The maximum rotor tip speed is generated when the rotor is moving in the direction of the flight path.
DYNAMICS Question 2: While the car in the figure is standing at point A above, it moves downward with a = 0.981-0.013v ^ 2 m / s ^ 2 acceleration. Find Vb, which is the velocity in the existence of point B. The unit of speed is m / s. Please be careful, thank you.
Please solve this, Thank you
