<h2>Explanation:</h2>

In physics, work is defined force that causes displacement. So this can be expressed by the following equation:

W=Fs

Where:

F:Force \\ \\ s:Displacement

The force can be found as:

F=ma \\ \\ F=5(10)=50N

And for the displacement:

s=6-2=4m

The force (weight) is down and the displacement is up, then the work must be negative. So:

W=-(50)(4) \\ \\ \boxed{W=-200J}

Morgarella [4.7K]
Area\ of\ base:A_B=169\pi\ ft^2\\\\A_B=\pi r^2\ \ \ (r-radius)\\\\\pi r^2=169\pi\ \ \ /:\pi\\\\r^2=169\\\\r=\sqrt{169}\\\\r=13\ (ft)\\\\H=2r\to H=2\cdot13=26\ (ft)

&#10;lateral\ area:A_L=2\pi rH\\\\A_L=2\pi\cdot13\cdot26=676\pi\ (ft^2)\\\\Surface\ area:A_S=2A_B+A_L\\\\A_S=2\cdot169\pi+676\pi=338\pi+676\pi=1014\pi\ (ft^2)

You are given that PS ≅ RS as indicated by the single has mark.

You are given that ∠PST ≅ ∠RST as indicated by the single arc.

You know the segment ST is congruent to itself by the reflexive property.

That is, you have two congruent sides and the angle between them, so you can claim the triangles are congruent by the SAS postulate.

Selection C is appropriate.
