A small block is placed over another block which is moving with a velocity of 5m/s. What is the absolute velocity of the small block?

(a) 5m/s

(b) 10m/s

(c) 0m/s

(d) 14m/s

This question was posed to me during a job interview.

The doubt is from Motion in a Straight Line topic in chapter Motion in a Straight Line of Physics – Class 11

The correct option is (a) 5m/s

For explanation: The absolute velocity of the small block is the same as that of the block moving with 5m/s. This is because absolute velocity is studied with respect to the ground frame. The relative velocity of the small block with respect to the other block is zero.
