Purpose of use
calculate d&d tom foolery of 720ft long jump moving at 50ft per turn(6second) and the height required to not grind off your feet.

Purpose of use
To understand the amount of impact I received
Comment/Request
35,000 lb Bulldozer tracking backwards at 6 mph. Tracked over a row of frozen ice 18"-24" inches tall. Instant impact and was injured. (Pretty much a free fall at the numbers indicated) Now I've been trying to wrap my head around what type of force I endured.
I apologize my equation is all over the place but anything close would help. If anyone sees this.
Thank you!

Purpose of use
Used to determine the distance from a well opening at ground level to the water level in the well. Turns out right at 100ft. We knew the total depth of the well was 278 ft, but wanted to calculate the volume of the column of water. 4 inches x 178 feet. So about 116 gal. Thanks for the help.

Purpose of use
Determining the height of the lava fountains of the Mauna Loa eruption. The free fall from apogee is 3.5 to 4.5 second so the fountain height is 200-350 feet high.

Purpose of use
Determine height of Ukrainian drone used to drop bomb on Russian forces if drop time was 4 seconds

Purpose of use
Acceleration of 1600km/h car at limit of sustained 4g for human survival - how long and how far?
Comment/Request
20 seconds a 4g would be super brutal, but reaching 1000mph in an achievable land speed record seems out of reach given different sites on earth.
Loved the DND comment.

Purpose of use
same as someone else posted, working out free fall distance for a DnD adventure

Purpose of use
Trying to explain to d&d player that if a rock fell for 5 seconds before hitting water in a dark sinkhole, that it would be at least 100m down and that he would be injured if not dead.

Thanks! This is exactly what we were looking for <3
