How do you calculate the peripheral speed when you know the rpm and radius of the blade?

After 1 revolution, the blade tip has travelled 2πr units of length (feet, metres etc)
So just multiply this figure by the number of revolutions per minute to get the peripheral distance travelled in a minute.
Bear in mind that this will give the answer if feet/metre per minute and you may then want to convert this into mph or kph.

How do you calculate the turning radius of a car?
I don't recall the exact formula, but, it involves the car's speed and the car's tires slip angle at a given speed.
How do you calculate schwarzcschild radius?
The Schwarzschild radius, rs, is given by rs = 2Gm/c2 where G is the gravitational constant, m is the mass of the object, and c is the speed of light in vacuum.

What is the centrifugal force on a turbine blade if a London bus is hanging from the blade?
A ball park figure for the weight of a double decker bus might be about 15,000 kilograms. But to calculate the centrifugal force on a turbine blade with this hanging from it would require the blade length and the rotational speed of the turbine.
In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
What is the centripetal acceleration of a stone with a radius of 0.75 meters and a height of 1.5 meters and travels a horizontal distance of 4 meters?
I don't think you have enough information. Here are two formulae to calculate centripetal acceleration: a = v2 / r a = omega2 x r (omega is the angular speed, in radians per second) Basically, apart from the radius you also need to know (or have enough information to calculate) the speed (or equivalently, the angular speed).
How many hours does it take to drive 574 miles?

If the maximum tension the rope can withstand before breaking is 126.8 N what is the maximum tangential speed the ball can have?
Not enough information. If the ball moves in a circle, you would also need the radius of the circle, and the mass of the ball.In this case, you can: 1) Calculate the corresponding centripetal acceleration, by using Newton's Second Law (a = F/m). 2) Calculate the tangential speed, using the formula for centripetal acceleration: acceleration = velocity squared / radius.
How can peripheral vision increase reading speed?
