A beam of light makes an angle of 27 o with the normal of a mirror made of 2.6- mm-thick glass silvered on the back. If the index of refraction of the glass is 1.50, how far is the point at which the beam leaves the glass surface (after being reflected from the silver backing) from the point at which the beam entered the glass? ( mm)
Suppose that in the same Atwood setup another string is attached to the bottom of m1 and a constant force f is applied, retarding the upward motion of m1. If m1 = 4.80 kg and m2 = 9.60 kg, what value of f will reduce the acceleration of the system..
