In a household experiment, Stephany uses a combination of string and spring to test their strengths, as shown in the figure. On the top end of the system is a football, and a spring-mass system is attached to the football with the help of a key. A needle attached to the spring lies next to the football. The final acceleration of this spring is more than 2g at the point of equilibrium. When the string is cut, the needle bursts the football. Calculate the acceleration of the blocks respectively at A, B and C just after the string is cut and also determine whether the ball bursts or remains safe

Figure below shows a mass-spring model of the type used to design packaging systems and vehicle suspensions, for example. The springs exert a force that is proportional to their compression, and the proportionality constant is the spring constant k. The two side springs provide additional resistance if the weight W is too heavy for the center spring. When the weight W is gently placed, it moves through a distance x before coming to rest. From statics, the weight force must balance the spring forces at this new position. (if x=d) These relations can be used to generate the plot of x versus W. (a) The following values are given: k1=104 N/m; k2 = 1.5 *104 N/m; d =0.1 m. Create a function that computes the distance x, using the input parameter W; Then, test your function for the following two cases, using the values: W=500 N W=2000 N. (b) Create another script and use your function to plot x versus W for 0 < W < 3000 N for the values of k1, k2, and d given in part a.
