The acceleration of a particle as seen from two frames S1 & S2 have equal magnitude 4m/s^2. (a) The frames must be at rest with respect to each other. (b) The frames may be moving with respect to each other but neither should be accelerated with respect to each other. (c) The acceleration of S2 with respect to S1 may either be 0 or 8m/s^2. (d) The acceleration of S2 with respect to S1 may be anything between 0 and 8m/s^2. THE ANSWER is given as (d) Well though d is correct i don’t understand why b can’t also be correct becauseap,s2 = a p,s1 + a s1,s2so since we have got both a p,s1 & ap,s2 4m/s2a s1,s2 should be ofcourse 0 i.e, neither should be accelerated with respect to the other.But the answer is only (d) . How ?
