The Table shows the displacement of a racing car at different times as it travels along a straight track during a speed trial. Displacement / m 0 85 170 255 340 Time / s 0 1 . 0 2 . 0 3 . 0 4 . 0 Draw the displacement-time graph and use it to find the car's velocity.

The graph between the displacement(distance and the time is shown above. From the graph, we can take any value of time and the corresponding distance covered by the car in that time. From the graph, we have the velocity = distance time = slope of V - T graph For example, the distance covered in time 2 sec is 170 m . Therefore, the slope of the graph 170 m 2 sec . = 85 m / sec

An old car travels due south.The distance it travels at hourly intervals is shown in the table Time / h 0 1 2 3 4 Distance / km 0 23 46 69 84 From the distance-time graph deduce the car's speed in kmh - 1 during the first three hours of the journey

The given data Time / h 0 1 2 3 4 Distance / km 0 23 46 69 84 Using the above data the graph is as follows. The time is taken on X - axis The distance is taken on y - axis From the graph it is evident that the distance travelled by the car during first three hours is 69 km . Therefore, the car's speed during this period= s = distance travelled time taken = 69 3 = 23 kmh - 1

An old car travels due south. The distance it travels at hourly intervals is shown in the table Time / h 0 1 2 3 4 Distance / km 0 23 46 69 84 What is the car's average speed in kmh - 1 during the whole journey,

The given data Time / h 0 1 2 3 4 Distance / km 0 23 46 69 84 Using the above data the graph is as follows. The time is taken on X - axis The distance is taken on y - axis From the graph it is evident that the distance travelled by the car during total journey= 84 km Therefore, the car's speed during this period= s = distance travelled time taken = 84 4 = 21 kmh - 1

Sketch a displacement - time graph to show your motion for the following event. You are walking at aconstant speed across a field after jumping off a gate, Suddenly you see a horse and stop. Your friend says there's no danger, so you walk on at a reduced constant speed. The horse neigh, and you run back to the gate. Explain how each section of the walk relates to a section of your graph.
