The acceleration as a function of time of a mass-spring system is given by a=(0.

Question

The acceleration as a function of time of a mass-spring system is given by a=(0.70m/s^2)sin[(3rad/s)t]. a)If the spring constant is 20N/m, what is the amplitude? b)What is the initial velocity?

Explanation / Answer

Amplitude = 0.7 / 9 = 7.78 cm

Initial velocity = 0.7 / 3 = 23.33 cm/s
