A physics book slides off a horizontal tabletop with a speed of $2.70\mathrm{m}/\mathrm{s}$. It strikes the floor in $0.350\mathrm{s}$. Ignore air resistance. Find the direction of book's velocity, just before the book reaches the floor. $?$ - below the $=$ horizontal Find the magnitude of book's velocity, just before the book reaches the floor.
