Question

2. The following table gives the data about motion of a car.
Time (h) 11.00 11.30 12.00 12.30 1.00
Distance (km) 0 30 30 65 100
Plot the graph.
(i) Find the speed of the car between 12.00 hours and 12.30 hours.
(ii) What is the average speed of the car?
(iii) Is the car’s motion an example of uniform motion? Justify.

Answer 1

Answer:

1. speed = distance time

65-30 km 30 min

| Speed = 1.67 km/min

2. Avg speed = total distance total time

$(distance)

100

65

30

1.00

11.30

12.00

12.30 t

(me)

3. In graph

you can see slope

120 min

i.e. ds dt V

20 Avg speed = 0.83 km/min

4 is not linea ie, straight Une hence the body is performing non unifarm motion.
