Silly putty is

A block with mass M attached to a horizontal spring with force constant k is moving with simple harmonic motion having amplitude A_(1) . At the instant when the block passes through its equilibrium position a lump of putty with mass m is dropped vertically on the block from a very small height and sticks to it. (a) Find the new amplitude and period. (b) Repeat part (a) for the case in which the putty is dropped on the block when it is at one end of its path.

A completely inelastic collision occurs between two balls of wet putty that move directly toward cach other along a vertical axis. Just before the collision, one ball, of mass 3.0 kg, is moving upward at 20 m/s and the other ball, of mass 2.0 kg, is moving downward at 10 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)

In this section each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences S1 : Of course, it is silly to try to overcome fears that keep us from destroying ourselves. S6 : The only fears you need to avoid are silly fears which prevent you from doing what you should do. P: This is sensible. Q : You wait until it is out of the way before crossing. R: You need some fears to keep you from doing foolish things. S: You are afraid of an automobile coming rapidly down the street you wish to cross. The proper sequence should be
