A $5\mathrm{.}00-$kg chandelier hangs from the ceiling of an elevator by a cable. The elevator

descends through a distance of $10\mathrm{.}0$ m in $2\mathrm{.}00$ s$.$ At the beginning of this time interval, it is moving at an unknown speed. By the end of the time interval, its speed has increased to $8\mathrm{.}00$ m$/$s$.$ It continues descending at a constant speed of $8\mathrm{.}00$ m$/$s thereafter. Calculate the tension in the cable while the elevator is speeding up and the tension after the speed of the elevator becomes constant.
