Same situation as in the previous two problems this time the magnet s mass is $6\mathrm{.}82$ kg and the magnetic force pulling it to the right is $67\mathrm{.}0$ N$.$ The length of the cord is $1\mathrm{.}04$ m$,$ and the ceiling is $3\mathrm{.}30$ m above the floor. Suppose that you cut the cord and the magnet falls to the floor while still being pulled to the right by the force of $67\mathrm{.}0$ N$.$ How long will it take the magnet to hit the floor?
