Dropping the ball!! (HEEEEEEEELP!) Okay. It has been YEARS since I've done stuff like this but I need a rough number estimate for a project I'm doing. Here is the situation: You have 20k wrecking ball you're dropping from 1m height. You're friend will catch it at the end of that 1m drop with only 0.15m to decelerate the mass to ZERO m/s. What is the rate of deceleration?? AND... what is the equivalent force needed to resist that type of deceleration in that super small time??? Sorry if these questions aren't even valid. Thanks in advanced for the answers!
