P5) Consider a horizontal spring, L0 = 60cm, with spring constant 10N/m to the movable end of which is attached a 2kg mass that is free to slide on a frictionless surface. At time t=0 the block is struck a sharp blow so that it has a speed of 0.75m/s towards the fixed end of the spring (but at t=0 it is still at the equilibrium position). As time passes the block executes simple harmonic motion. Find a) the amplitude of the motion, b) the maximum acceleration of the block, and c) the maximum velocity of the block.

P6) We saw in class that the standing waves that can form on string of length L that has its ends fixed are characterised by having wavelengths such that an integral number of half wavelengths fit on the string. That is, they are all of the form nλ/2=L where n is an integer. If the speed of waves on the string is v deduce the the frequencies of the allowed standing waves and comment on their relationship to each other.
