(II) Two vectors, V₁ (→ above V₁) and V₂ (→ above V₂) , add to a resultant Vᵣ (→ above Vᵣ) = V₁ (→ above V₁) + V₂ (→ above V₂). Describe V₁ (→ above V₁) and V₂ (→ above V₂) if 


(b) V²ᵣ = V²₁ + V²₂, 

(III) You are given a vector in the xy plane that has a magnitude of 95.0 units and a y component of ― 60.0 units. (a) What are the two possibilities for its 𝓍 component? (b) Assuming the 𝓍 component is known to be positive, specify the vector which, if you add it to the original one, would give a resultant vector that is 80.0 units long and points entirely in the ― 𝓍 direction. 

(II) At t = 0, a particle starts from rest at 𝓍 = 0 , y = 0 and moves in the xy plane with an acceleration a (→ above a) = (4.0 î + 3.0 ĵ ) m/s². Determine 

(a) the 𝓍 and y components of velocity,
