An 8-kg mass is attached to a spring hanging from the ceiling and allowed to come to rest. assume that the spring constant is 40 n/m and the damping constant is 4 n-sec/m. at time =0, an external force of =4cos(+) is applied to the system. formulate the initial value problem describing the motion of the mass and determine the amplitude and period of the steady-state solution.

force tends to be low and long diustance masses are high

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
