A train start from rest. Its velocity become 40 ms-1in 10 s. Its acceleration will be:

4 ms-2

4 ms-1

40 ms-1

40 ms-2

Distance covered by freely falling downward body is first second is:

5 m

29.4 m

19.6 m

If an object is moving with constant speed then its distance time graph will be a straight line

Along time axis

Along distance axis

Parallel to time axis

Inclined to time axis

A straight line parallel to time axis on a distance time graph tells that object is:

Moving with constant speed

At rest

Moving with variable speed

In motion
