A 19 kg weight is attached to a spring with constant k = 475 kg/m and subjected to an external force F ( t ) = 1197 sin ( 2 t ) . The weight is initially displaced 2 meters above equilibrium and given an upward velocity of 3 m/s. Find its displacement for t > 0, with y ( t ) measured positive upwards.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
