Motion In A Plane

Question
CBSEENPH11020750

A particle shows distance -time curve as given in this figure. The maximum instantaneous velocity of the particle is around the point

  • B

  • C

  • D

  • A

Solution

A.

B

The particle has maximum instantaneous velocity at that point at which its slope is maximum.
Therefore, vmax = dx/dt = maximum slope
From the figure, it is obvious that at point C, the slope is maximum, hence at this point velocity is maximum.
