STANDARD Physics Relative Velocity MCQ Question
A ball A is dropped from a building of height 45 m. Simultaneously another identical ball B is thrown up with a speed 50 m s⁻¹. The relative speed of ball B w.r.t. ball A at any instant off time is (Take g = 10 m s⁻²)
0
10 m s⁻¹
25 m s⁻¹
50 m s⁻¹
Correct Answer
Detailed Explanation
As there is no acceleration of ball B w.r.t. ball A, the relative speed of ball B w.r.t ball A at any instant of time remains constant (50 m s⁻¹).
