A) \[-12m/s\]
B) \[12m/s\]
C) \[-7.6m/s\]
D) \[7.6m/s\]
Correct Answer: C
Solution :
Given, Velocity of balloon\[u=12m/s\] Time\[t=2\sec \]when die packet is released from the balloon it acquires the velocity of balloon it means initial velocity of the packet\[~=12m/s\] Hence, velocity after \[2\sec \] is given by, \[v=u+at\] \[=12+(-9.8)\times 2\] \[=12-19.6=-7.6\,\,m/s\](minus sign is due to the motion is in opposite direction)You need to login to perform this action.
