Let's consider the system given in Figure 2. The end of a flexible spring with spring constant k is attached to the wall and the other end to a block of mass m. There is no friction between the block and the inclined plane. When the spring is at its natural length, the block is first decelerated. The angle of inclination of the inclined plane is given as ß. a) What is the acceleration of the blog when the spring is extended by x?
