A block of mass m is attached to a spring whose spring constant is k. The other end of the spring is fixed so that when the spring is unstretched, the mass is located at x=0. http://session.masteringphysics.com/problemAsset/1007151/26/5247.jpg . Assume that the x direction is to the right
The mass is now pulled to the right a distance A beyond the equilibrium position and released, at time t=0, with zero initial velocity.
Assume that the vertical forces acting on the block balance each other and that the tension of the spring is, in effect, the only force affecting the motion of the block. Therefore, the system will undergo simple harmonic motion.
---------------------
Specify when the magnitude of the acceleration of the block reaches its maximum value. Consider the following options:
1. only once during one period of motion,
2. when the block's speed is zero,
3. when the block is in the equilibrium position,
4. when the block's displacement equals either A or -A,
5. when the block's speed is at a maximum.
