An object undergoes an acceleration of 8 ms^-2 starting from rest. Distance traveled in 1 s is :

A body goes from A to B with a velocity of 20 m/s and comes back B to A with a velocity of 30m/s.

The average velocity of the body during the whole journey is

If an object covering distances in direst proportion to the square of time lapsed, then the acceleration is

Distance travelled by a freely falling body is proportional to :-
