1. A spring is such that a 4-lb weight stretches the spring 0.40 ft. The 4-lb weight is
attached to the spring (suspended from a fixed support) and the system is allowed to
reach equilibrium. Then the weight is started from equilibrium position with an
imparted upward velocity of 2 ft/sec. Assume that the motion takes place in a medium
that furnishes a retarding force of magnitude numerically equal to the speed, in feet
per second, of the moving weight. Determine the position of the weight as a function
of time.

- 2. A platform edge x(1) section of a uniform chain of length 8 ft is loosely wound around a peg at the edge of a high horizontal platform, and the remaining part of the chain hangs still on the edge of the platform. The length of the extended chain is 3 ft, the chain weighs 2 Ib/ft, and the positive direction is downwards. Starting at t = 0 seconds, the weight of the outstretched part causes the chain on the table to slip smoothly and fall to the floor. If x(t) represents the length of the chain protruding into the table at time t = 0, then v = dx/dt is the velocity.
