What is the ratio of displacement to distance for a moving object?
An object travels 10m North and then 10m East. What is the magnitude of its displacement?
A body covers first half of total distance with speed v1 and second half with speed v2. The average speed is:

A bullet is fired into a target and loses half its velocity after penetrating 3cm. How much further will it penetrate before coming to rest?
The velocity of a body increases from 5 m/s to 15 m/s while covering a distance of 20m. Find the acceleration.
If the displacement of a body is proportional to the square of time, then the body is moving with:
