Askydiver jumped out of a plane, determine distance he descended after 5 seconds. gravity is pulling him down at 10 m/s^2 (air resistance is negligible).

125 m

Explanation:

This problem is related to vertical motion and can be solved with the following equation:

(1)

Where:

is the difference between the final height and initial height . Let's take into account the initial height is greater than the final height, since the skydiver is descending.

Is the skydiver's initial velocity, assuming the plane was not moving at that moment

is the time

is the acceleration due gravity

Solving the equation:

(2)

(3)

(4) Here, the negative sign only indicates the position of the skydiver, and remember the initial height is greater than the final height.

In fact, the distance is positive: 125 m
