2018 AP PHYSICS 1 FREE-RESPONSE QUESTIONS Q Feeeee P 2m (a) Determine the numerical value of the ratio TpQ/Tp. m to 5. (7 points, suggested time 13 minutes) Block Pof mass m is on a horizontal, frictionless surface and is attached to a spring with spring constant k. The block is oscillating with period Tp and amplitude Ap about the spring's equilibrium position xo. A second block Qof mass 2m is then dropped from rest and lands on block P at the instant it passes through the equilibrium position, as shown above. Block Q immediately sticks to the top of block P, and the two-block system oscillates with period Tpo and amplitude App.
