Answer:

15,000 J

Step-by-step explanation:

Since the lift also carries the man, the total weight of the man+lift system is

[tex]F=300 N + 950 N = 1250 N[/tex]

The work done in moving the lift upward is

[tex]W=Fd[/tex]

where

F is the weight of the lift+man combined system

d is the displacement

In this problem,

F = 1250 N

d = 12 m

Substituting,

[tex]W=(1250)(12)=15,000 J[/tex]
