List of top Physics Questions on Relative Velocity asked in MHT CET

Two girls are standing at the ends 'A' and 'B' of a ground where $AB = b$. The girl at 'B' starts running perpendicular to 'AB' with velocity $V_1$. The girl at 'A' starts running simultaneously with velocity $V_2$ and in shortest distance meets the other girl in time 't'. The value of 't' is ______.
A spaceship moves with a velocity of 5000 m/s. What is the relativistic factor \( \gamma \) for the spaceship? (Given that \( c = 3 \times 10^8 \, \text{m/s} \))
Two objects A and B are separated horizontally by distance ' a '. Object B moves in a direction perpendicular to distance ' a ' with velocity ' \( V_1 \) '. Simultaneously object A covers shortest distance with velocity ' V ' and meets object B in time ' t '. The time ' t ' is given by
