MCQ
A car is travelling in the north direction. To stop, it produces a deceleration of $60\ m/ s^2$. Which of the following is a correct representation for the deceleration?
  • A
    $60\ m/ s^2$ Northwards
  • $60\ m/ s^2$ Southwards
  • C
    $60\ m/ s^2$ Eastwards
  • D
    $60\ m/ s^2$ Westwards

Answer

Correct option: B.
$60\ m/ s^2$ Southwards
Deceleration always acts in the direction opposite to the direction of motion.
Magnitude of deceleration is $60\ m/ s^2$ and it acts in the direction opposite to North.
Hence the answer is $60\ m/ s^2$ Southwards.
