Question

A package is dropped from a helicopter that is moving upward at15m/s. If it takes 8.0 sec before the package strikes the ground, how high above the ground was the package when it was released? Neglect air resistance.

Answer 1

313.6 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Time (t) = 8 s

Acceleration due to gravity (g) = 9.8 m/s²

Height (h) =?

The height at which the package was dropped can be obtained as follow:

h = ½gt²

h = ½ × 9.8 × 8²

h = 4.9 × 64

h = 313.6 m

Thus, the package was at a height of 313.6 m when it was dropped.
