A passenger in a helicopter traveling upwards at 20 m/s accidentally drops a package out the window. If it takes 8 seconds to reach the ground, how high to the nearest meter was the helicopter when the package was dropped?

Damon
h = Hi + Vi t  4.9 t^2
0 = Hi + 20 (8)  4.9(64)
0 = Hi + 160  314
Hi = 154 meters
