Shm problem driving me crazy I don't understand how finding the velocity of an object undergoing SHM can be so difficult. Here's the problem: A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position y1 such that the spring is at its rest length. The object is then released from y1 and oscillates up and down, with its lowest position being 10 cm below y1. (a) What is the frequency of the oscillation? (b) What is the speed of the object when it is 8 cm below the initial position? (c) An object of mass 300 g is attached to the first object, after which the system oscillates with half its original frequency. What is the mass of fist object? (d) Relative to y1, whe
