Q. A block of mass m = 2.00 kg is dropped from height h = 90 cm onto the spring of spring constant k = 1960 N/m. Find out the maximum distance the spring is compressed.
Q. A beam of partially polarized light can be considered to be the mixture of polarized and unpolarized light. Assume we send such a beam throughout a polarizing filter and then rotate the filter through 360° while keeping it perpendicular to the beam. If the transmitted intensity varies by a factor of 4.50 all through the rotation, what fraction of the intensity of original beam is associated with the beam's polarized light?
