Exercise 6.1
The graph shows how the velocity of a van changes during a short journey. Find the distance travelled by the van.
Exercise 6.2
The graph below shows how the velocity of a train changes as it travels along a straight railway line.
a) Find the total distance travelled by the train in the 180 seconds..
b) Find the acceleration of the train on the first stage of the motion.
Exercise 6.3
The diagram shows a velocity-time graph for a lift.
a) Find the total distance travelled by the lift.
b) Calculate the acceleration of the lift during the last 2 seconds.

Answer a | Answer b | Answer c | Solution a | Solution b | Solution c
Exercise 6.4
As a train travels 500 m its speed increases from 5
a) Find the acceleration of the train.
b) Find the time it takes the train to travel this distance.
Exercise 6.5
A cyclist accelerates at 0.5
a) Find the distance travelled by the cyclist during the 10 seconds and the speed that she reaches at the end of this period of time.
b) After the 10 seconds her acceleration changes to 0.2
Exercise 6.6
As a van travels along a straight road its speed increases from 9
