Question

Vectors V₁ and V₂ shown above have equal magnitudes. The vectors represent the velocities of an object at times t₁, and t₂, respectively. The average acceleration of the object between time t₁ and t₂ 

(A) zero 

(B) directed north 

(C) directed west 

(D) directed north of east 

(E) directed north of west

Answer 1

Correct option (E) directed north of west

Acceleration is proportional to ∆v. ∆v = v₂ – v₁ = v₂ + (– v₁).
