Answer:
The work done will be [tex]W=55.27\: J[/tex]
Explanation:
The work equation is given by:
[tex]W=F\cdot x[/tex]
Where:
F is the force due to gravity (weight = mg)
x is the length of the ramp (3 m)
Now, the force acting here is the component of weight in the ramp direction, so it will be:
[tex]F_{x-direction}=mgsin(28)[/tex]
Therefore, the work done will be:
[tex]W=mgsin(28)*3[/tex]
[tex]W=4*9.81*sin(28)*3[/tex]
[tex]W=55.27\: J[/tex]
I hope it helps you!
