An object is initially traveling at a velocity of 12 m/s. It then begins to change it’s velocity according to the function ?=2.5?+3? v = 2 . 5 s + 3 a , where v is the velocity of the object, s is the objects position, and a is the acceleration. Determine the velocity of the object 30 meters after the velocity begins to change. (17.5 m/s)

When you shine a light on an object, the momentum from the photons that make up that light impacts the object. For macroscopic objects, this will have no measurable effect. Describe why this is different for atomic-sized objects. Suppose you shine a very long wavelength light on one electron and a very short wavelength light on another electron. What differences will you observe? Why does shining very short wavelength photons on an electron not tell you exactly where the electron...
