Apotter's wheel of radius 11 cm starts from rest and rotates with constant angular accel- eration until at the end of 35 s it is moving with angular velocity of 19 rad/s. what is the angular acceleration? answer in units of rad/s2.

angular acceleration = 0.54 rad/s/s

Explanation:

Initial angular speed of the wheel is ZERO as it starts from rest

final angular speed is given as

now we know that angular acceleration is rate of change in angular speed

here we have

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
