1) In a playground, a wooden horse is attached to the ground by a stiff spring. When a 27 kg child sits on the horse, the spring compresses by 9 cm. With the child sitting on the horse, the spring oscillates up and down with a frequency of 0.88 Hz. What is the oscillation frequency of the spring when no one is sitting on the horse?
2)The period of oscillation of a spring-and-mass system is 0.53 s and the amplitude is 4.0 cm. What is the magnitude of the acceleration at the point of maximum extension of the spring?
