A 0.400-kg object attached to a spring with a force constant of 8.00 N/m vibrates in simple harmonic motion with an amplitude of 12.2 cm. The maximum speed is 54.6 cm/s. CALCULATE THE MAXIMUM VALUE OF ITS ACCELERATION
A 1.50-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 5.60sin(2?t), where F is in newtons and t is in seconds. The force constant of the spring is 29.0 N/m. The resonance angular frequency of the system is 4.4 s^-1. The angular frequency of the driven system is 6.28 s^-1. FIND THE AMPLITUDE OF THE MOTION.
