A 0.20-kg block is suspended from a vertical spring, it stretches the spring 10 cm from its unstrained length. The same block and spring are placed on a horizontal, frictionless surface, as shown. The block is then pulled 15 cm from its unstrained length and released at time t= 0 s. It then undergoes SHM.
What is the frequency of the horizontal SHM?
What is the maximum acceleration of the block, and where in its motion does that max accel. occur?
If the block is pulled so that the spring stretches 30 cm and released (instead of 15 cm), What are the frequency and acceleration of the block?
