Answer:t=0.3253 s
Explanation:
Given
speed of balloon is
speed of camera
Initial separation between camera and balloon is
Suppose after t sec of throw camera reach balloon then,
distance travel by balloon is
and distance travel by camera to reach balloon is
Now
There are two times when camera reaches the same level as balloon and the smaller time is associated with with the first one .
(b)When passenger catches the camera time is
velocity is given by
and position of camera is same as of balloon so
Position is
