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/sThis 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

Answer»

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.
