Question

A man moves from A to B in a straight line and then moves from B to C where C is the mid point of the line. If the average velocity of the particle from A to C through B is v. Let the average speed of the particle for this motion is kv . The value of k .

TestHub · Accepted Answer

​ (i) Average velocity = ⟨ V ⟩ = time displacement ​ ​ V = t x ​ ​ ​ (ii) Average speed = time distan ce ​ ⇒ k v = t ( 2 x + x ) ​ k v = t 3 x ​ k v = 3 v ∴ k = 3 ​
