Two blocks A and B having mass m = 1 kg and M = 4 kg respectively are attached to a spring and placed vertically on a weighing machine as shown in the figure. Block A is held so that the spring is relaxed. A is released from this position and it performs simple harmonic motion with angular frequency w = 25 rad s^(-1) . The spring remains vertical (a) Find the reading of the weighing machine as a function of time. Take t = 0 when A is released. (b) What is the maximum reading of the weighing machine ?
