(a)8.34s and (b )699.81m
Explanation:
Horizontal component of the velocity of decoy is
Horizontal displacement of decoy from release point is
So the time of flight
Initial vertical component (downward) of the velocity of decoy is
Taking acceleration due to gravity
The net vertical displacement during time of flight which is the
height of the release point is given by
