Question

an object Travels 30 metre in 4 seconds and then another 30 metres in 2 second is the data given above sufficient to find average velocity of the object​

Answer 1

Given:

An object Travels 30 metre in 4 seconds and then another 30 metres in 2 second.

To find:

If this data is sufficient to find average velocity of the object.

Concept:

Average velocity is defined as the ratio of total displacement to the total time taken. Since the term "Displacement" is in the definition ,we can say that average velocity is a vector quantity.

$\boxed{ \sf{avg \: v = \dfrac{total \: displacement}{total \: time} }}$

The data provided in the question is insufficient because of the following reason:

• The direction of the displacement vector is not specified.

• If both the displacements are in same direction then the average velocity comes as 10 m/s.

• If the displacement vectors in opposite direction then average velocity comes as 0 m/s.

Hence the data is insufficient.

Answer 2

Answer:

the data is insufficient to find average velocity of the object
