प्रश्न
The accelerations of a particle as seen from two frames S1 and S2 have equal magnitude 4 m/s2.
विकल्प
The frames must be at rest with respect to each other.
The frames may be moving with respect to each other.
The acceleration of S2 with respect to S1 may either be zero of 8 m/s2.
The acceleration of S2 with respect to S1 may be anything between zero and 8 m/s2.
उत्तर
The acceleration of S2 with respect to S1 may be anything between zero and 8 m/s2.
Explanation:
\[\vec{a}_{\text{ s}_2 \text{ s } _1} = \vec{a}_{\text{s }_2 \text{ p } } + \vec{a}_{\text{p} \text{s}_1} \]
\[\left| \vec{a}_{\text{ s } _2 \text{ s } _1} \right| = \sqrt{4^2 + 4^2 + 32\cos\left( \theta \right)}\]
\[- 1 < \cos\left( \theta \right) < 1\]
