Explanation / Answer

Apply Newton second law to the elvator

T- mg = F net

T- mg= ma

T = m( g+a)

---------------------------------------------------------

a= T- mg/ m = 12750-1200(9.8)/1200

=0.825 m/s^2

moving upward with this accleration

slowing down as it moves downwards
speeding up as it moves upwards

options are correct answer
