The force that the lift exerts on the mass is equal to 900,000N.
Why?
We can solve the problem by using the following formula:
[tex]Work=Force*Distance\\\\Work=Force*Height\\[/tex]
We know that:
[tex]Work=1.8x10^{6} J\\Height=2m[/tex]
So, calculating we have:
[tex]Force=\frac{Work}{Height}\\\\Force=\frac{1.8x10^{6}J }{2m}=900000N[/tex]
Hence, we have that the force that the lift exerts on the mass is equal to 900,000N.
Have a nice day!
