Solve the problem.An object of mass m attached to a coiled spring with damping factor b is pulled down a distance a from its rest position and then released. Assume the positive direction of the motion is up and the period of the first oscillation is T. Write an equation that relates the distance d of the object from its rest position after t seconds. m = 15 g; a = 11 cm; b = 0.7 g/sec; T = 3 sec
What will be an ideal response?
d = -11e-0.7t/30 cos
