Q6 of 35 Page 55

Using the velocity-time graph prove that v2 – u2 = 2as.

Consider the following velocity-time graph


Distance travelled by an object in time t = s


s = Area of trapezium OABE




Acceleration = a = slope of velocity time graph AB




Hence,




EB = v


ED = u




Hence proved from velocity time graph that

A ball which is thrown vertically upwards reaches the roof of a house 100m high. At the moment this ball is thrown vertically upward, another ball is dropped from rest vertically downward from the roof of the house. At which height the ball will pass each other?
