A 4.0 kg food pack was dropped from a height of 200 m by a helicopter during flood relief operations. At what velocity will the food pack be falling halfway to the ground?

Explanation:

Given:

Distance, s = 100 m

Initial velocity, u = 0 m/s

Acceleration, a = 9.8 m/s^2

Using equations of motion,

V^2 = u^2 + 2as

V = sqrt(2 × 9.8 × 100)

= 44.47 m/s

Velocity at halfway down to the ground is 44.45 m/s and as tge food package keeps going down(dustance to the ground reduces), the velocity increases.

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

0.11 m/s and 0.28 m/s should be correct
