Chapter 3 – Motion in a Straight Line

A car is moving along a straight road with a uniform acceleration. It passes through two points P and Q separated by a distance with velocity 30 km/h and 40 km/h respectively. The velocity of the car midway between P and Q is? A body dropped from top of a tower falls through 40 m [...]
