The package was released 82 m above ground. With no air resistance, and acceleration due to gravity = 9.81, time it takes is
82 = (1/2)gt²
t=sqrt(2*82/9.81)
= 4.089 s.
During this time, the helicopter has travelled 96 m horizontally, therefore
Velocity of helicopter = 96/4.089=23.48m/s
82 = (1/2)gt²
t=sqrt(2*82/9.81)
= 4.089 s.
During this time, the helicopter has travelled 96 m horizontally, therefore
Velocity of helicopter = 96/4.089=23.48m/s
