A) 195 m/s
B) 160 m/s
C) 105 m/s
D) 140 m/s
Correct Answer: C
Solution :
\[{{\overrightarrow{v}}_{car,van}}=192-30=162km/h=45m/s\] \[\therefore \]\[{{\overrightarrow{v}}_{bullet,car}}={{\overrightarrow{v}}_{bullet,gun(van)}}+{{\overrightarrow{v}}_{gun(van),car}}\] \[=150-45=105\text{m/s}\]You need to login to perform this action.
