A 20-lb weight is suspended from the end of a vertical spring having a spring constant of 40 Ib/ft and is allowed to reach equilibrium. It is then set into motion by stretching the spring 2 in from its equilibrium position and releasing the mass from rest. Find the position of the weight at any time t if there is no external force and no air resistance.
A block of 1:6 kg mass is on a plane inclined to 50 for which the kinetic friction coecient is c = 0:12. The block is connected to a spring of constant k = 5 N=m by a string. The latter passes without slipping through a pulley which is assimilated to a 1 kg disc having a radius of 0:15 m. If the system is initially at rest and the spring has a zero elongation, what is the module of the speed of the block when it has slipped by 0:Five feet down the incline?
A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below. The rod is attached to the floor via a hinge and makes an angle of 70° relative to the ground; a massless string is also attached to the rod at the ¼ point of the rod and makes an angle of 20° relative to the horizontal. What tension must be provided by the rope so that the system remains in stationary? If at some point the string breaks, what will be the angular acceleration of the system the instant that the string breaks?
