Question

Figure shows the position of a particle moving along the x-axis as a function of time. Which of the following is correct?

• A. The particle has come to the rest $6$ times
• B. The maximum speed is at $t=6$ $s$
• C. The velocity remains positive for $t=0$ to $t=6$ $s$
• D. The average velocity for the total period shown is negative.

Answer 1

The correct option is A The particle has come to the rest $6$ times

At six points in the graph the tangents have zero slope i.e. velocity is zero.
