Final answer:
The equation for the velocity of the object in damped oscillation can be found by taking the derivative of the displacement equation.
Step-by-step explanation:
To find the equation for the velocity of the object, we can start with the displacement equation x(t) = X cos(2πt).
Taking the derivative of this equation with respect to time will give us the velocity equation.
Using the product rule, we get v(t) = - 2πX sin(2πt).
So, the equation for the velocity of the object is v(t) = - 2πX sin(2πt)
