A toy car moves along a straight track as described below:
• It stays at a fixed point 2m from the origin from t=0s to t=3s.
• It then travels uniformly and reaches 14m at t=7s.
• After that, it again remains at the same position till t=10s.
Answer the following questions.
(i) Draw a position–time graph for the entire motion, taking suitable scales on both axes.
(ii) What physical quantity is represented by the slope of the graph during the interval 3s to 7s? Explain briefly.
(iii) Is the motion of the car uniform over the whole 10s? Give reason based on the graph you have drawn.
(iv) Identify the time interval(s) during which the speed of the car is zero.
