The 25-lb box slides on the surface for which = 0.25. The box has a velocity = 15 ft/s when it is 2 ft from the plate. If it strikes the smooth plate, which has a weight of 12 lb and is held in position by an unstretched spring of stiffness = 410 lb/ft, determine the maximum compression imparted to the spring. Take = 0.75 between the box and the plate. Assume that the plate slides smoothly.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
