An object has an initial velocity u and an acceleration a. The object moves in a straight line through a displacement s and has final velocity v. The above quantities are related by the equation shown. v² = u² + 2as Which condition must be satisfied in order for this equation to apply to the motion of the object?
AThe direction of a is constant and the direction of a is the same as the direction of s.
BThe direction of a is constant and the direction of a is the same as the direction of u.
CThe magnitude of a is constant and the direction of a is constant.
DThe magnitude of a is constant and the direction of a is the same as the direction of v.
