A $1500$ kg elevator, suspended by a single cable with tension $16\mathrm{.}0$ kN $,$ is measured to be moving upward at $\backslash (3\mathrm{.}0\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ Air resistance is negligible.

Is the elevator speeding up$,$ slowing down, or moving at constant speed?

constant speed

slowing down

speeding up

Part B

We want to find the elevator's speed after traveling upward $10\mathrm{.}0$ m $.$ This could be solved with Newton's laws and kinematics, but we will use the energy principle. How much work does tension do on the elevator as it rises $10\mathrm{.}0$ m $?$

Express your answer with the appropriate units.
