Q1. A train 400 m long is moving on a straight track with a speed of 84.90km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.5km/h. assuming constant acceleration, resolve how long the train blocked the crossing. Disregard the width of crossing.

Q2. Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 1.9nC, are separated by the distance of 60 cm. An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. What is the final speed of electron when it is 10 cm form charge 1?
