Expert Solution
Step 1

Given  data- 

Mass(M)=1000 kg 

Distance moved by mass is d=1000 m  along 450 to direction of gravitational force. We have to find the work done.

Acceleration due to gravity g=9.81 m/s2

Let displacement of mass be d 

Gravitational force acts always downward F=Mg

We have θ=450 be the angle between F and d
