Question

Figure shows x-t graph of a particle. Find the time t such that average velocity og the particle during the period is 0 to t is zero. ​

Answer 1

Answer:

Explanation:

Average velocity in t second will be zero if the displacement at time t will remain equal to the displacement at t=0 which is 20 m. So we draw a line parallel to the time axis from 20 m on displacement axis to meet the curve at P (See the figure below). From P draw a line perpendicular to time axis PQ. The time at Q gives the instant when the displacement is again 20 m and average velocity zero. From eye estimation, t=12 s at Q.

Answer 2

Answer:

AT T=12 SEC V . avg is 0.........
