If the velocity varies parabolically, how does the acceleration vary?(a) Linearly(b) Hyperbolically(c) Parabolically(d) EllipticallyI got this question in an online quiz.My question is from Motion in a Straight Line topic in portion Motion in a Straight Line of Physics – Class 11

Answer»

Correct choice is (a) Linearly

To explain I would say: VELOCITY varies parabolically IMPLIES that velocity is of the FORM at + bt^2. On differentiating the velocity, we GET the equation for acceleration. THEREFORE, a = dv/dt = a+2bt, which is a linear equation. Hence the acceleration varies linearly.
