Exercise 21 - 6

1. A car is parked 10 m from home for 10 minutes. Draw a displacement-

time, velocity-time and acceleration-time graphs for the motion. Label all

the axes.

2. A bus travels at a constant velocity of 12 m·s−^1 for 6 seconds. Draw

the displacement-time, velocity-time and acceleration-time graph for the

motion. Label all the axes.

3. An athlete runs with a constant acceleration of 1 m·s−^2 for 4 s. Draw

the acceleration-time, velocity-time and displacement time graphs for the

motion. Accurate values are only needed for the acceleration-time and

velocity-time graphs.

4. The following velocity-time graph describes the motion of a car. Draw the

displacement-time graph and the acceleration-time graph and explain the

motion of the car according to the three graphs.

the displacement-time graph and the acceleration-time graph and explain
the motion of the truck according to the three graphs.
