A box with mass m is placed on top of a box with mass 2m as
shown in the figure. An external force F (t) = αt, where α is a
positive constant, acts on the bottom block and causes it to
accelerate from rest at t = 0. The two blocks have coefficient of
static friction μ between them, and the bottom box slides on a
frictionless surface. At what time will the top block begin to
slide relative...
