A) 3 m/s2 upward
B) 5 m/s2 upward
C) 3 m/ s2 downward
D) none of the above
Correct Answer: D
Solution :
Consider downward direction as positive \[{{\overrightarrow{a}}_{AP}}=-{{\overrightarrow{a}}_{BP}}\] \[{{\overrightarrow{B}}_{AG}}={{\overrightarrow{a}}_{AP}}+{{\overrightarrow{a}}_{PG}}\] \[3={{\overrightarrow{a}}_{AP}}-2\] \[\Rightarrow \]\[{{\overrightarrow{a}}_{AP}}=5m/{{s}^{2}}\] \[\therefore \]\[{{\overrightarrow{a}}_{BG}}={{\overrightarrow{a}}_{BP}}+{{\overrightarrow{a}}_{PG}}\]\[=-5-2=-7\text{m/}{{\text{s}}^{\text{2}}}\]
