Question

A train travelling with uniform acceleration crosses an electric pole with the velocities 20 ms−1 and 30 ms−120 ms−1 and 30 ms−1 respectively. Find the velocity of train when its mid-point crosses the electric pole ?​

Answer 1

Answer:

by formolu

vM=root of (v1)*2+(v2)*2. /2

(20)*2+(30)*2/2

40000+90000/2

130000/2

65000
