The given figure shows dots on a ticker tape after performing an experiment. The value of acceleration for the bracket region X will be

Correct answer: A. a < 0

  • A. a < 0
  • B. a = 0
  • C. a > 0
  • D. 0 < a < 1

Explanation

A) a < 0: This is correct. A decreasing distance between marks implies deceleration, which means the acceleration is negative.

About Acceleration

Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
