Question
A particle moves with uniform acceleration and v1 , v2 and v3 denote the average velocities in the three successive interval of time t1, t2 and t3. Which of the following relations is correct ?
Options
A.(v1 - v2) : (v2 - v3) = (t1 - t2) : (t2 + t3)
B.(v1 - v2) : (v2 - v3) = (t1 + t2) : (t2 + t3)
C.(v1 - v2) : (v2 - v3) = (t1 - t2) : (t2 - t3)
D.(v1 - v2) : (v2 - v3) = (t1 - t2) : (t1 - t3)
Solution
When acceleration is constant the instantaneous velocity is equal to the average velocity in mid of the time interval.
