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.

313.6 m

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.

answer: good job it's all correct !

explanation:

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
