Question

1. A body travels a distance of 15m from A to B and then moves a distance of 20m at right angles to AB. Calculate the total distance travelled and the displacement.
2. An athlete completes one round of a circular track of diameter 70 m in 30s. Find
the distance travelled by the athlete (ii) the magnitude of displacement of the athlete at
the end of 30 s. [1]

3. A motor cyclist drives from A to B with a uniform speed of 30 km/h and returns back
with a speed of 20 km/h. Find his average speed of travel. [1]
4. Sneha swims a 100m long pool back & forth and covers 200 m in 1 minute and 40 s
along the same straight path. Find the average speed and average velocity of Sneha.
7. Write three differences between distance and displacement. [1]
8. An object has moved through a distance. Can it have zero displacement? If yes,
support your answer with an example. [1]
9. What does the path of an object look like when it is in uniform motion? [1]
