1.	A block of mass M connected to an ideal spring of force constant k, is placed on a smooth surface. The block is pushed to the left so as to compress the spring by a length A and then it is released. The block hits an elastic wall at a distance `(3A)/(2)` from its point of release. Assume the collision to be instantaneous. (a) Calculate the time required by the block to complete one oscillation (b) Draw the velocity - time graph for one oscillation of the block. (c) Find the value of k for which average force experienced by the wall due to repeated hitting of the block is `F_(0)`.
Answer» Correct Answer - (a)`(4pi)/(3)sqrt((M)/(k))`, (c ) `k=(4pi F_(0))/(3sqrt(3)A)`
