Question

A particle has a rectilinear motion and the figure gives
its displacement as a function of time Which of the
following statements are true with respect to
the motion?
O In motion between Oto A the velocity is positive and acceleration is
negative
0 Between A and B the velocity and acceleration are positive
0 Between and the velocity is negative and acceleration is negative
0 Between D and the velocity is negative and acceleration is positive​
pls if u know then ans

Answer 1

Answer:

Between B and C, the velocity is negative and acceleration is negative

Explanation:

When the particle displacement is maximum or minimum, the velocity is 0. When the displacement is 0, particle velocity is either maximum or minimum. Similarly, the particle acceleration is maximum (or minimum) when the particle displacement is minimum (or maximum), respectively.
