You have the displacement. Surely you know that the velocity is the time derivative of displacement, and that acceleration is the time derivative of velocity...
Could someone please tell me how to calculate the following...?
The angular displacement Θ radians of a flywheel varies with time seconds and follows the equation Θ
a)The angular velocity and acceleration of the flywheel when time = 1 Second
b) The time when the angular acceleration is zero.
Many thanks in advance.
The rate of change of the angular displacement is the angular velocity.
The rate of change of the angular velocity is the angular acceleration
(rate of change of velocity).
Differentiate your displacement expression to get the velocity expression.
Whatever new expression you get for velocity, differentiate that to get the acceleration expression.
