The propeller of an aircraft accelerates from rest with an angular acceleration α = 7t + 8, where α is in rad/s2 and t is in seconds. What is the angle in radians through which the propeller rotates from t = 1.00 s to t = 6.10 s?

The value  is  

Explanation:

From the question we are told that

    The angular acceleration is  

    The first time is  

    The second time

Generally the angular velocity is mathematically represented as

=>  

=>  

Generally the angular displacement  is mathematically represented as

=>  

=>  

=>

=>

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

find the surface area of the sphere to the nearest square unit. use a calculator.
