Two frames of reference `P` and `Q` are moving relative to each other at constant velocity. Let `vecv_(OP)` and `veca_(OP)` represent the velocity and the acceleration respectively of a moving particle `O` as measured by an observer in frame `P` and `vecV_(OQ)` and `veca_(OQ)` represent the velocity and the acceleration respectively of the moving particle `O` as measured by an observer in frame `Q`, then

Options

A. `vecv_(OP)=vecv_(OQ)`
B. `vecv_(OP)=vecv_(OQ)+vecv_(QP)`
C. `veca_(OP)=veca_(OQ)`
D. `veca_(OP)=veca_(OQ)+veca_(QP)`

Answer

B, C, D

Explanation

`barr_(OQ)=barr_(PR)+barr_(OP),barr_(OQ)=barr_(PQ)+barr_(OP),barr_(OQ)=bara_(OQ)=barO+bara_(OP)`
