Which of the following velocity-time graph represents infinite acceleration?
Correct answer: A. Straight line normal to the time-axis
- A. Straight line normal to the time-axis
- B. Straight line inclined to the time axis at an angle of 45°
- C. Straight line parallel to the time axis
- D. Straight line inclined to the time axis at an angle of 135o
Explanation
The correct answer is Option A: A straight line normal to the time-axis represents infinite acceleration. This is because the graph shows an instantaneous change in velocity occurring without any time elapsing, resulting in an infinite slope, which translates to infinite acceleration. Option B represents constant positive acceleration, Option C indicates zero acceleration, and Option D represents negative acceleration or deceleration. None of these depict infinite acceleration as required by the question.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
