Study the vector diagram. Three vectors are drawn tail to tip method in the x y plane. Vector labeled T starts at the origin and is drawn in the northeast direction. The second vector is labeled U and drawn in the south south east direction. The third is labeled V and drawn in the north northeast direction. X and Y components are drawn for each vector along the x and y axis.

Which formula can be used to find the x-component of the resultant vector?

Tx - Ux - Vx
Tx + Ux + Vx
Tx = Tcosθ
Tx = Tsinθ

Astone weighing 1.5 kilograms is resting on a rock at a height of 20 meters above the ground. the stone rolls down 10 meters and comes to rest on a patch of moss. the gravitational potential energy of the stone on the moss is joules.
