A block with mass 1 kg attached to a horizontal spring with force constant 20 N/cm is moving with simple harmonic motion having amplitude 5 cm. At the instant when the block passes through its equilibrium position, a lump of putty with mass 300 g is dropped vertically onto the block from a very small height and sticks to it.

(c) Repeat part (a) for the case in which the putty is dropped on the block when it is at the end of its path What are the new amplitude and period?
