Question

A particle is moving in a straight line with initial velocity u and uniform acceleration a. If the sum of the distances travelled in nth and (n + 1)th seconds is 100 m, then its velocity after n seconds, in m/s is

Answer 1

Explanation:

A particle is moving in a straight line with initial velocity u and uniform acceleration f. If the sum of the distances travelled in t^(th) and (t + 1)^(th) seconds is 100 cm, then its velocity after t seconds, in cm//s, is. u+ft=100/2⇒v=50cm/s.
