Divide the change in speed by the time.

The opening in the tracheal respiratory system is the brronchi.
The opening of the urethra is the external urethral orifice.
Urine is expelled via the urethra located above the vaginal opening.
The small opening of the iris in the eye is the pupil.
The opening in called a urethra, in both males and females.
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!

80 m/s2 up
To calculate this, you divide the change in velocity, by the time.

Only if they have a heart attack, but not likely.

He will decelerate (meaning an acceleration in the direction opposite of current velocity) at a rate of (54 m/s - 4 m/s)/.75 seconds = 66.67 m/s2. This is about 6.8 Gs.
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
Skydivers in different freefall orientations fall at different speeds:Wingsuiting - 25 to 60mphBelly to earth - typical for formation skydiving - 120mphFreefly headup and headdown - 150 to 190mphSpeed skydiving - 200 to 327mphFor each of these disciplines, experience, jumpsuit worn, weight & height all make subtle differences to exact freefall speeds. During any typical skydive, speeds vary a lot.
Mile High Skydivers in Longmont, Colorado opens up at 9:00 AM Friday to Sunday during the winter months. They close at sunset. In the summer time, the hours increase to Thursday-Friday 9:00am- Sunset and Saturday-Sunday 8:00am- Sunset.
