Question

The diagram below shows the pattern of the oil dripping on the road at a constant
rate from a moving car.
By observing the above diagram, answer the following questions.
a. What information do you get from it about the motion of the car.
b. Plot distance – time graph corresponding to the motion of the car.
c. How the speed of the car can be calculated by the graph?

Answer 1

Answer:

but where is the diagram

Answer 2

Answer:

Since oil is dropping from the car at a constant rate, distance between consecutive oil drops tells us about the speed of the car. Suppose the time interval between fall of two consecutive drops is t. If the distance between two consecutive drops is d, then speed of the car is v= d/t.

Initially, car is moving with constant speed, but later value of d starts decreasing, which means car is slowing down.
