What is the work done if a Boulder of mass 100 kilogram is rolled 40 meter up slope an angle of 20 degrees assuming the force of friction is negligible​

The work done is 13680.8 J.

Explanation:

The work done can be calculated as follows:

Where:            

F: is the force                                                        

d: is the displacement = 40 m                                    

The force acting on the boulder is given by:

Where:

m: is the mass = 100 kg

g: is the acceleration due to gravity = 10 m/s²

θ: is the angle = 20°      

Then, the work is:

Therefore, the work done is 13680.8 J.  

I hope it helps you!  

i need the answer to this too but idk it ; -;

e) none of the above answers are correct
