Question

The accelerations of a particle as seen from two frames S1 and S2 have equal magnitude 4m/*.

(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 the other.

(c) The acceleration of S2 with respect to S1 may either be zero or 8 m/*

(d) The acceleration of S2 with respect to S1 may be anything between zero and 8m/s2.

Answer 1

(d) The acceleration of S2 with respect to S1 may be anything between zero and 8m/s2.

Explanation:

The acceleration of S2 with respect to S1 is given by a= ap,s1 - ap,s2 , This vector sum can be easily understood by the following figure:--
