A small motor runs a lift that raises aload of bricks weighing 836N to a height of 10.7m in 23.2s. assuming that the bricks are lifted with constant speed, what is the minimum power the motor must produce?

Physics 
drwls,
Power required =
(Potential Energy Gain)/(time)
= 836*10.7/23.2
The answer will be in Watts.
